You must create a tunnel interface and bind it
to the security zone (vpn) that you created in Configuring a Security Zone. Then you can bind the VPN to the tunnel
interface in the VPN configuration.
To configure a tunnel interface to be used for
the VPN:
Select Configuration > Quick Configuration > Interfaces. A list of the network interfaces available on the router appears,
as shown in Figure 133. The third column indicates
whether the interface has been configured.
