To configure the Cisco VPN 500x to support LAN-to-LAN connections, it is necessary to define the tunnel configuration, as well as the IP communication parameters that are used in the tunnel. This is accomplished in two sections, the [Tunnel Partner VPN x] section, and the [IP VPN x] section. For any given site-to-site configuration, the (x) defined in these two sections must match, so that the tunnel configurations are properly associated with the protocol configuration.
