Thanks

[Mithrandir]

Thanks to everyone who helped achieve this configuration.

Here's an example of 2 cisco 2500 series routers who are connected to each
other with their serial interface.
IN A CLOSED LAN ENVIRONMENT. (no internet connection)

Special Thanks to Pim, he devoted a lot of his precious time for us, and
explained the mechanics of Tunneling.

Thank you all.
Greetings
Mithrandir and Johan.
