An example of Cisco Easy VPN comprehensive configuration is shown in this example. The topology is 15-15. In this example, the Cisco 831 router is used as the remote device of Easy VPN and the Cisco 1751

gateway points to the network port interface address of the link balancing device. Step 2: create a virtual-server on the Link balancing device. Its VIP address is the public network address of the vpn server. The associated service-group has only one server, the private address of the vpn server. Enable DSR for the virtual-server. Step 3: Create a loopback address on the firewall, which is the public ip a
