> 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.
> 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:

> 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 upgrading to Release 8.3, for every readdress server rule in an inbound IPv4 ACL, customers must now add a permit rule to an outbound ACL that explicitly permits packets from the readdress rule's redirect address and port number. If customers omit this permit rule, the system will reject all packets destined for the subscriber's UE from the readdress rule's redirect address and port number.

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.

> 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:

> dest_host_address
> The IP address of the destination host to filter against expressed in 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 any 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 198.162.100.25 any fragment
> The following sets the insertion point before the rule defined above:
> before redirect nexthop 192.168.10.4 context 23 ip host 198.162.100.25 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 198.162.100.25 any fragment
> The following deletes the first rule defined above:
> no redirect nexthop 192.168.10.4 context 23 ip host 198.162.100.25 any fragment
> redirect nexthop (by TCP/UDP packets)
> Used to redirect subscriber sessions based on the transmission control protocol/user datagram protocol packets sent by the source to the mobile node or the network.
