Remote Access Configuration Wizard

Use the Remote Access Configuration wizard to configure your device with the policies that enable it to act as a remote access VPN server.

Depending on the device type, you must configure a user group or tunnel group policy first. A user group policy is configured on an IOS security router, PIX Firewall, or Catalyst 6500/7600 device. Tunnel group policies are configured on ASA devices or PIX Firewalls version 7.0. Other policies are then assigned to the device. These can be factory default policies provided by Security Manager or shared policies that were created in Security Manager. See Assigning the Default Remote Access VPN Policies, page 11-11.


Note You cannot use the wizard to edit a remote access VPN. Each time you launch the wizard, any previous user group (or tunnel group) policy assignment is removed from the device, and you must create it again.

Fragmentation Settings

Fragmentation mode

Supported on Cisco IOS routers and Catalyst 6500 /7600 devices.

Fragmentation minimizes packet loss in a VPN tunnel when packets are transmitted over a physical interface that cannot support the original size of the packet.

Select the required fragmentation mode option from the list:

No Fragmentation—Select if you do not want to fragment prior to IPsec encapsulation.

End to End MTU Discovery—Select to use ICMP messages for the discovery of MTU.

End-to-end MTU discovery uses Internet Control Message Protocol (ICMP) messages to determine the maximum MTU that a host can use to send a packet through the VPN tunnel without causing fragmentation.

Local MTU Handling—Select to set the MTU locally on the devices. This option is typically used when ICMP is blocked.

Local MTU Size

Supported on Cisco IOS routers and Catalyst 6500 /7600 devices, when Local MTU Handling is the selected fragmentation mode option.

Note The permitted MTU size is between 68 and 65535 bytes depending on the VPN interface.

DF Bit

Supported on Cisco IOS routers, Catalyst 6500 /7600 devices, PIX 7.0 and ASA devices.

A Don't Fragment (DF) bit is a bit in an IP header that determines whether a device is allowed to fragment a packet.

Select the required setting for the DF bit:

Copy—To copy the DF bit from the encapsulated header in the current packet to all the device's packets. If the packet's DF bit is set to fragment, all packets will be fragmented.

Set—To set the DF bit in the packet you are sending. A packet that exceeds the MTU will be dropped and an ICMP message sent to the packet's initiator.

Clear—To cause the device to fragment packets regardless of the original DF bit setting. If ICMP is blocked, MTU discovery fails and packets are fragmented only after encryption.

Enable Fragmentation Before Encryption

Supported on Cisco IOS routers, Catalyst 6500 /7600 devices, PIX 7.0 and ASA devices.

When selected, enables fragmentation before encryption, if the expected packet size exceeds the MTU.

Lookahead Fragmentation (LAF) is used before encryption takes place to calculate the packet size that would result after encryption, depending on the transform sets configured on the IPsec SA. If the packet size exceeds the specified MTU, the packet will be fragmented before encryption.

Enable Notification on Disconnection

Supported on PIX 7.0 and ASA devices.

When selected, enables the device to notify qualified peers of sessions that are about to be disconnected. The peer receiving the alert decodes the reason and displays it in the event log or in a pop-up window. This feature is disabled by default.

IPsec sessions may be dropped for several reasons, such as, a security appliance shutdown or reboot, session idle timeout, maximum connection time exceeded, or administrator cut-off.

Enable Spoke-to-Spoke Connectivity through the Hub

Supported on PIX 7.0 and ASA devices.

When selected, enables direct communication between spokes in a hub-and-spoke VPN topology, in which the hub is an ASA or PIX 7.0 device.

ASA Cluster Load Balance Page

Use the Cluster Load Balance page to enable load balancing for an ASA device in your remote access VPN.


Note Load balancing requires an active 3DES/AES license. The ASA device checks for the existence of this crypto license before enabling load balancing. If it does not detect an active 3DES or AES license, the device prevents load balancing, and also prevents internal configuration of 3DES by the load balancing system.


Navigation Path

1. Click the Device View button on the toolbar.

2. From the Device selector, select the device on which you want to configure load balancing.


Note You can configure load balancing only on a n ASA device.


3. Select Remote Access VPN > ASA Cluster Load Balance from the Policy selector.


Note You can also open the Cluster Load Balance page from Policy view. For more information, see Managing Shared Remote Access VPN Policies in Policy View, page 11-35.

VPN Load Balancing

Participate in Load Balancing Cluster

Select to specify that the device belongs to the load-balancing cluster.

VPN Cluster Configuration

Cluster IP Address

The single IP address that represents the entire virtual cluster. The IP address should be in the same subnet as the external interface.

UDP Port

The UDP port for the virtual cluster in which the device is participating. If another application is using this port, enter the UDP destination port number that you want to use for load balancing.

The default is 9023.

Enable IPsec Encryption

Select this check box to ensure that all load-balancing information communicated between the devices is encrypted.

When the check box is selected, you must also specify and verify a shared secret. The security appliances in the virtual cluster communicate via LAN-to-LAN tunnels using IPsec.

IPsec Shared Secret

The shared secret to be communicated between IPsec peers if you enabled IPsec encryption. This can be a case-sensitive value between 4 and 16 characters, without spaces.

Priority

Accept default device value

When selected (the default), accepts the default priority value assigned to the device.

Configure same priority on all devices in the cluster

When selected, enables you to configure the same priority value to all the devices in the cluster. The priority indicates the likelihood of this device becoming the virtual cluster master, either at startup or when the existing master fails.

Enter a value between 1 and 10.

VPN Server Configuration
