Cisco VPN 3000 Series Concentrators Interoperability Profile

Configuring a LAN-to-LAN IPSec Connection

Step 1 In the Name field, enter a unique, descriptive name for this LAN-to-LAN connection. The maximum

length is 32 characters. Since the created rules and SA use this name, we recommend that you keep it

short. In this example, the name is A to B.

Step 2 In the Interface field, make sure that the interface that displays is the configured public interface on the

VPN Concentrator for this end of the LAN-to-LAN connection, 14.15.16.17. If not, from the Interfaces

drop-down menu, choose this IP address. The list shows all interfaces that have the Public Interface

parameters enabled.

Step 3 In the Peer field, enter the IP address of the remote peer in the LAN-to-LAN connection, 22.23.24.25.

This is the IP address of the public or WAN interface on the peer IPSec VPN device.

Step 4 In the Preshared Key field, enter the shared secret for this VPN connection, hr5xb8416aa9r6.

Step 5 From the Authentication drop-down menu, select ESP/SHA/HMAC-160.

Step 6 In the Encryption field, verify that the entry is 3DES-168. If not, from the Encryption drop-down menu,

choose this value.

Step 7 In the IKE Proposal field, verify that the entry is VPNC IKE A to B. If not, from the IKE Proposal

drop-down menu choose this value.
