# ACL Configuration Mode Commands

The Access Control List Configuration Mode is used to create and manage IP-based, user access privileges.

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
deny/permit (by source IP address masking)

Filters subscriber sessions based on the IP address mask sent by the source to the mobile node or the network.

after

Indicates that all rules defined subsequent to this command are to be inserted after the command identified by the exact options listed.

This moves the insertion point to be immediately after the rule which matches the exact options specified such that new rules will be added, in order, after the matching rule.

IMPORTANT:

If the options specified do not exactly match an existing rule, the insertion point does not change.
before

Indicates that all rules defined subsequent to this command are to be inserted before the command identified by the exact options listed.

This moves the insertion point to be immediately before the rule which matches the exact options specified such that new rules will be added, in order, before the matching rule.

IMPORTANT:

If the options specified do not exactly match an existing rule, the insertion point does not change
no

Removes the rule which exactly matches the options specified.
deny | permit

Specifies the rule is either block (deny) or an allow (permit) filter.

- deny: Indicates the rule, when matched, drops the corresponding packets.
- permit: Indicates the rule, when matched, allows the corresponding packets.

log

Default: packets are not logged.

Indicates all packets which match the filter are to be logged.
source_address

The IP address(es) from which the packet originated. IP addresses must be entered in IPv4 dotted-decimal format.

This option is used to filter all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.
source_wildcard

This option is used in conjunction with the source_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.

IMPORTANT:

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
Usage:

Define a rule when any packet from the IP addresses which fall into the group of addresses matching the IP address masking. This allows the reduction of filtering rules as it does not require a rule for each source and destination pair.

IMPORTANT:

The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide.
Example:
The following command defines two rules with the second logging filtered packets:

    permit 1.2.3.0 0.0.0.31

    deny log 1.2.4.0 0.0.0.15

The following sets the insertion point before the first rule defined above:

    before permit 1.2.3.0 0.0.0.31

The following command sets the insertion point after the second rule defined above:

    after deny log 1.2.4.0 0.0.0.15

The following deletes the first rule defined above:

    no permit 1.2.3.0 0.0.0.31

deny/permit (any)

Filters subscriber sessions based on any packet received. This command is also sets the access control list insertion point.

Usage:

Define a catch all rule to place at the end of the list of rules.

IMPORTANT:

It is suggested that any rule which is added to be a catch all should also have the log option specified. The logged packets may be used to determine if the current list of rules is adequate or needs modification to ensure proper security. The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide.

source_address

The IP address(es) from which the packet originated. IP addresses must be entered in IPv4 dotted-decimal format.

This option is used to filter all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.

- One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.

IMPORTANT:

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
any

The IP address of the destination host to filter against expressed in IPv4 dotted-decimal notation.
dest_address

The IP address(es) to which the packet is to be sent.

This option is used to filter all packets to a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this parameter. The range can then be configured using the dest_wildcard parameter.
dest_wildcard

This option is used in conjunction with the dest_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the dest_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the dest_address parameter must be ignored.

IMPORTANT:

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
icmp_type

Specifies that all ICMP packets of a particular type are to be filtered. The type can be an integer value between 0 and 255.
icmp_code

Specifies that all ICMP packets of a particular code are to be filtered. The type can be an integer value between 0 and 255.
Usage:

Define a rule to block ICMP packets which can be used for address resolution and possible be a security risk.

The IP filtering allows flexible controls for pairs of individual hosts or groups by IP masking which allows the filtering of entire subnets if necessary.

IMPORTANT:

The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide.
Example:
The following commands define two rules with the second logging filtered packets:

    before permit icmp
    host 10.2.3.4 any 168

The following command sets the insertion point after the second rule defined above:

    after deny log icmp
    10.2.3.0 0.0.0.31 host 10.2.4.16 168 11

The following deletes the first rule defined above:

    deny log udp 10.2.3.0
    0.0.0.31 10.2.4.127 0.0.0.127

The following sets the insertion point before the first rule defined above:

    before permit tcp
    host 10.2.3.4 any

The following command sets the insertion point after the second rule defined above:

    after deny log udp

redirect_address

The IP address to which the IP packets are redirected. TCP or UDP packet headers are rewritten to contain the new destination address. This must be an IPv4 address specified in dotted-decimal notation.
port port_no

The number of the port at the redirect address where the packets are sent. TCP or UDP packet headers are rewritten to contain the new destination port number.
tcp | udp

Specifies the redirect is to be applied to the IP based transmission control protocol or the user datagram protocol.

- tcp: Redirect applies to TCP packets.
- udp: Redirect applies to UDP packets.

source_address

The IP address(es) from which the packet originated.

This option is used to filter all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.
source_wildcard

This option is used in conjunction with the source_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.

IMPORTANT:

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
any

Specifies that the rule applies to all packets.
host

Specifies that the rule applies to a specific host as determined by its IP address.
source_host_address

The IP address of the source host to filter against expressed in IPv4 dotted-decimal notation.
dest_host_address

The IP address of the destination host to filter against expressed in IPv4 dotted-decimal notation.
eq source_port

Specifies a single, specific source TCP port number to be filtered.

source_port must be an integer from 0 through 65535.
gt source_port

Specifies that all source TCP port numbers greater than the one specified are to be filtered.

source_port must be an integer from 0 through 65535.
lt source_port

Specifies that all source TCP port numbers less than the one specified are to be filtered.

neq source_port

Specifies that all source TCP port numbers not equal to the one specified are to be filtered.

source_port must be an integer from 0 through 65535.
dest_address

The IP address(es) to which the packet is to be sent.

This option is used to filter all packets to a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this parameter. The range can then be configured using the dest_wildcard parameter.
dest_wildcard

This option is used in conjunction with the dest_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the dest_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the dest_address parameter must be ignored.

IMPORTANT:

For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
eq dest_port

Specifies a single, specific destination TCP port number to be filtered.

dest_port must be an integer from 0 through 65535.
gt dest_port

Specifies that all destination TCP port numbers greater than the one specified are to be filtered.

dest_port must be an integer from 0 through 65535.
lt dest_port

Specifies that all destination TCP port numbers less than the one specified are to be filtered.

dest_port must be an integer 0 through 65535.
neq dest_port

Specifies that all destination TCP port numbers not equal to the one specified are to be filtered.

dest_port must be an integer 0 through 65535.
Usage:

Use this command to define a rule that redirects packets to a different destination address. The TCP and UDP packet headers are modified with the new destination address and destination port.

IMPORTANT:

The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide.

IMPORTANT:

Prior to Release 8.3, for packets received from the packet data network destined for a subscriber's UE, the system applied logic to reset the source address of a packet to the original destination address of the input packet before applying the outbound access control list (ACL). In Release 8.3 and higher, the system reverses the order and applies the outbound ACL before resetting the source address. This change impacts all current readdress server rules in inbound IPv4 ACLs.

IMPORTANT:

After Release 8.3, for every readdress server rule in an inbound IPv4 ACL, you must add a permit rule to an outbound ACL that explicitly permits packets from the readdress rule's redirect address and port number. If the permit rule is omitted, the system will reject all packets destined for the subscriber's UE from the readdress rule's redirect address and port number.
Example:
The following command defines a rule that redirects packets to the server at 192.168.10.4, UDP packets coming from any host with a destination of any host are matched:

    readdress server 192.168.10.4
    udp any any

The following sets the insertion point before the rule defined above:

    before readdress server
    192.168.10.4 udp any any

The following command sets the insertion point after the first rule defined above:

    after readdress server
    192.168.10.4 udp any any

The following deletes the rule defined above:

    no readdress server

Usage:

Define a rule when any packet from the IP addresses which fall into the group of addresses matching the IP address masking. This allows the reduction of redirect rules as it does not require a rule for each source and destination pair.

IMPORTANT:

The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide.

IMPORTANT:

Also note that “redirect” rules are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.
Example:
The following command defines a rule that redirects packets to the context with the context ID of 23 and the source IP and wildcard of 192.168.22.0 and 0.0.0.31:

    redirect context 23

Also note that “redirect” rules are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.
Example:
The following command defines a rule that redirects packets to the context with the context ID of 23, and IP packets coming from the host with the IP address 198.162.100.25, and fragmented packets for any destination are matched:

    redirect context 23 ip
    host 198.162.100.25 any fragment

The following sets the insertion point before the rule defined above:

    before redirect context
    23 ip host 198.162.100.25 any fragment

The following command sets the insertion point after the first rule defined above:

    after redirect context
    23 ip host 198.162.100.25 any fragment

The following deletes the first rule defined above:

    no redirect context
    23 ip host 198.162.100.25 any fragment

redirect context (by TCP/UDP packets)

Redirects subscriber sessions based on the transmission control protocol/user datagram protocol packets sent by the source to the mobile node or the network.

source_address

The IP address(es) from which the packet originated.

This option is used to filter all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.
source_wildcard

This option is used in conjunction with the source_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.

IMPORTANT:

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.

source_port must be an integer from 0 through 65535.
dest_address

The IP address(es) to which the packet is to be sent.

This option is used to filter all packets to a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this parameter. The range can then be configured using the dest_wildcard parameter.
dest_wildcard

This option is used in conjunction with the dest_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the dest_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the dest_address parameter must be ignored.

IMPORTANT:

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.

IMPORTANT:

The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide. Also note that “redirect” rules are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.
Example:
The following command defines a rule that redirects packets to the context with the context ID of 23, and UDP packets coming from any host are matched:

    redirect context 23
    udp any

The following sets the insertion point before the rule defined above:

    before redirect context
    23 udp any

The following command sets the insertion point after the first rule defined above:

    after redirect context
    23 udp any

icmp_type

Specifies that all ICMP packets of a particular type are to be filtered. The type can be an integer value between 0 and 255.
icmp_code

Specifies that all ICMP packets of a particular code are to be filtered. The type can be an integer value between 0 and 255.
Usage:

Define a rule definition to block ICMP packets which can be used for address resolution and possibly be a security risk.

The IP redirecting allows flexible controls for pairs of individual hosts or groups by IP masking which allows the redirecting of entire subnets if necessary.

IMPORTANT:

A maximum of 16 rule definitions can be configured per ACL. Also note that “redirect” rule definitions are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.

Define a rule definition when any packet from the IP addresses which fall into the group of addresses matching the IP address masking. This allows the reduction of filtering rule definitions as it does not require a rule definition for each source and destination pair.

IMPORTANT:

A maximum of 16 rule definitions can be configured per ACL.
Example:
The following command defines a rule definition to redirect packets to a charging service named chgsvc1:

    redirect css service
    chgsvc1 10.2.3.0 0.0.0.31

redirect css service (by TCP/UDP packets)

Redirects subscriber sessions based on the transmission control protocol/user datagram protocol packets sent by the source to the mobile node or the network (Content Service Steering).

Indicates all rule definitions defined subsequent to this command are to be inserted before the command identified by the exact options listed.

This moves the insertion point to be immediately before the rule definition which matches the exact options specified such that new rule definitions will be added, in order, before the matching rule definition.

IMPORTANT:

If the options specified do not exactly match an existing rule definition, the insertion point does not change.

css service service_name

The name of the active charging service to which packets are to be redirected. At the executive mode prompt, use the show active-charging service all command to display the names of all configured charging services.

service_name must be an alphanumeric string from 1 through 15 characters.
downlink

Apply this rule definition only to packets in the downlink (from the Mobile Node) direction.
log

Default: packets are not logged.

Indicates all packets which match the filter are to be logged.
source_address

The IP address(es) from which the packet originated.

This option is used to filter all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.
source_wildcard

This option is used in conjunction with the source_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.

IMPORTANT:

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
Usage:

Define a rule definition when any packet from the IP addresses which fall into the group of addresses matching the IP address masking. This allows the reduction of filtering rule definitions as it does not require a rule definition for each source and destination pair.

IMPORTANT:

A maximum of 16 rule definitions can be configured per ACL.
Example:
The following command defines a rule definition to redirect packets to a charging service named chgsvc1:

    redirect css service
    chgsvc1 downlink 10.2.3.0 0.0.0.31

redirect css service (for downlink, by TCP/UDP packets)

Redirects subscriber sessions to a charging service based on the transmission control protocol/user datagram protocol packets in the downlink (from the Mobile Node) direction (Content Service Steering).

This option is used to filter all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.
source_wildcard

This option is used in conjunction with the source_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.

IMPORTANT:

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.

icmp_type

Specifies that all ICMP packets of a particular type are to be filtered. The type can be an integer value between 0 and 255.
icmp_code

Specifies that all ICMP packets of a particular code are to be filtered. The type can be an integer value between 0 and 255.
Usage:

Define a rule definition to block ICMP packets which can be used for address resolution and possibly be a security risk.

The IP redirecting allows flexible controls for pairs of individual hosts or groups by IP masking which allows the redirecting of entire subnets if necessary.

IMPORTANT:

A maximum of 16 rule definitions can be configured per ACL. Also note that “redirect” rule definitions are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.
Example:
The following command defines a rule definition that redirects packets to the charging service named chgsvc1, and ICMP packets in the uplink (to the Mobile Node) direction from the host with the IP address 198.162.100.25:

    redirect css service
    chgsvc1 uplink icmp host 192.168.100.25

Apply this rule definition only to packets in the uplink (to the Mobile Node) direction.
log

Default: packets are not logged.

Indicates all packets which match the filter are to be logged.
source_address

The IP address(es) from which the packet originated.

This option is used to filter all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.
source_wildcard

This option is used in conjunction with the source_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.

Usage:

Define a rule definition when any packet from the IP addresses which fall into the group of addresses matching the IP address masking. This allows the reduction of filtering rule definitions as it does not require a rule definition for each source and destination pair.
Example:
The following command defines a rule definition to redirect packets to a charging service named chgsvc1:

    redirect css service
    chgsvc1 uplink 10.2.3.0 0.0.0.31

This option is used in conjunction with the source_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.

IMPORTANT:

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
Usage:

Define a rule when any packet from the IP addresses which fall into the group of addresses matching the IP address masking. This allows the reduction of redirect rules as it does not require a rule for each source and destination pair.

IMPORTANT:

The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide.

IMPORTANT:

Also note that “redirect” rules are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.
Example:
The following command defines a rule that redirects packets to the next hop host at 192.168.10.4, the context with the context ID of 23 and the source IP and wildcard of 192.168.22.0 and 0.0.0.31:

This option is used to filter all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.
source_wildcard

This option is used in conjunction with the source_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.

IMPORTANT:

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.

icmp_type

Specifies that all ICMP packets of a particular type are to be filtered. The type can be an integer value between 0 and 255.
icmp_code

Specifies that all ICMP packets of a particular code are to be filtered. The type can be an integer value between 0 and 255.
Usage:

Define a rule to block ICMP packets which can be used for address resolution and possible be a security risk.

The IP redirecting allows flexible controls for pairs of individual hosts or groups by IP masking which allows the redirecting of entire subnets if necessary.

IMPORTANT:

The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide.

IMPORTANT:

Also note that “redirect” rules are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.
Example:

after

Indicates all rules defined subsequent to this command are to be inserted after the command identified by the exact options listed.

This moves the insertion point to be immediately after the rule which matches the exact options specified such that new rules will be added, in order, after the matching rule.

IMPORTANT:

If the options specified do not exactly match an existing rule, the insertion point does not change.
before

Indicates all rules defined subsequent to this command are to be inserted before the command identified by the exact options listed.

This moves the insertion point to be immediately before the rule which matches the exact options specified such that new rules will be added, in order, before the matching rule.

IMPORTANT:

If the options specified do not exactly match an existing rule, the insertion point does not change.
no

Removes the rule which exactly matches the options specified.
nexthop nexthop_addr

The directly connected IP address to which the IP packets are forwarded.
context context_id

The context identification number of the context to which packets are redirected. At the executive mode prompt, use the show context all command to display context names and context IDs.
interface interface_name

The name of the logical interface to which the packets should be redirected. interface_name must be an alphanumeric string from 1 through 79 characters.
log

Default: packets are not logged.

Indicates all packets which match the redirect are to be logged.
source_address

The IP address(es) from which the packet originated.

This option is used to filter all packets from a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this option. The range can then be configured using the source_wildcard parameter.
source_wildcard

This option is used in conjunction with the source_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the source_address parameter must be ignored.

IMPORTANT:

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
any

Specifies that the rule applies to all packets.
host

Specifies that the rule applies to a specific host as determined by its IP address.
source_host_address

The IP address of the source host to filter against expressed in IPv4 dotted-decimal notation.
dest_host_address

The IP address of the destination host to filter against expressed in IPv4 dotted-decimal notation.
dest_address

The IP address(es) to which the packet is to be sent.

This option is used to filter all packets to a specific IP address or a group of IP addresses.

When specifying a group of addresses, the initial address is configured using this parameter. The range can then be configured using the dest_wildcard parameter.
dest_wildcard

This option is used in conjunction with the dest_address option to specify a group of addresses for which packets are to be filtered.

The mask must be entered as a complement:

- Zero-bits in this parameter mean that the corresponding bits configured for the dest_address parameter must be identical.
- One-bits in this parameter mean that the corresponding bits configured for the dest_address parameter must be ignored.

IMPORTANT:

The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore, allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and 0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
fragment

Indicates packet redirection is to be applied to IP packet fragments only.
protocol num

Indicates that the packet filtering is to be applied to a specific protocol number.

num can be an integer ranging from 0 to 255.
Usage:

Block IP packets when the source and destination are of interest.

IMPORTANT:

The maximum number of rules that can be configured per ACL varies depending on how the ACL is to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide.

IMPORTANT:

Also note that “redirect” rules are ignored for ACLs applied to specific subscribers or all subscribers facilitated by a specific context.
Example:
The following command defines a rule that redirects packets to the next hop host at 192.168.10.4, the context with the context ID of 23, and IP packets coming from the host with the IP address 198.162.100.25, and fragmented packets for any destination are matched:

    redirect nexthop 192.168.10.4
    context 23 ip host 192.168.100.25 any fragment

The following sets the insertion point before the rule defined above:

    before redirect nexthop
    192.168.10.4 context 23 ip host 192.168.100.25 any fragment

The following command sets the insertion point after the first rule defined above:

    after redirect nexthop
    192.168.10.4 context 23 ip host 192.168.100.25 any fragment

The following deletes the first rule defined above:

    no redirect nexthop
    192.168.10.4 context 23 ip host 192.168.100.25 any fragment

redirect nexthop (by TCP/UDP packets)

Redirects subscriber sessions based on the transmission control protocol/user datagram protocol packets sent by the source to the mobile node or the network.
