Enhanced Easy VPN

The following sections describe the Cisco Router and Security Device Manager
configuration screens for Enhanced Easy VPN.
Specify the router interface to which the virtual template interface is to be
unnumbered, and specify the method to use for authentication in this window.
A virtual template interface must be unnumbered to a router interface to obtain an
IP address.
Cisco recommends that you unnumber the virtual template interface to a loopback
address for greatest flexibility. To do this, click Unnumbered to new loopback
interface and enter an IP address and subnet mask for the loopback interface. A
sample loopback IP address and subnet mask is 127.0.0.1, 255.255.255.0.
To unnumber the virtual template interface to another interface, click
Unnumbered to and choose the interface. You should choose the interface that
terminates the tunnel on the router. Click Details to view IP address,
authentication, policy, and other information about the interface that you are
choosing.
