If you're referring to the 192.168.13.0/24 network, there is no need to
allow it, and it won't show up unless you redistribute connected or make it
part of a routing protocol. The addresses of the tunnel itself are, ummm...
"tunneled" through the IP network that connects the source and destination.
The tunnel looks like one hop.
