To simplify the process of connecting remote VPN clients to the UTM, use the Mode Config feature to assign IP addresses to remote users automatically, including a network access IP address, subnet mask, WINS server, and DNS address. Remote users are given IP addresses available in a secured network space so that remote users appear as seamless extensions of the network.

Mode Config Operation

After the IKE Phase 1 negotiation is complete, the VPN connection initiator (which is the remote user with a VPN client) requests the IP configuration settings such as the IP address, subnet mask, WINS server, and DNS address from the UTM. The Mode Config feature allocates an IP address from the configured IP address pool and activates a temporary IPSec policy, using the information that is specified in the Traffic Tunnel Security Level section of the Mode Config record (on the Add Mode Config Record screen that is shown in Figure 185 on page 314).

Note: After configuring a Mode Config record, you need to configure an IKE policy manually, and select the newly created Mode Config record from the Select Mode Config Record drop-down list (see

Configure Mode Config Operation on the UTM on page 312). You do

not need to change any VPN policy.

Note: An IP address that is allocated to a VPN client is released only after the VPN client has gracefully disconnected or after the SA liftetime for the connection has timed out.

Configure Mode Config Operation on the UTM

To configure Mode Config on the UTM, first create a Mode Config record, and then select the Mode Config record for an IKE policy.
