I am running a gateway using rip, etc.  I really only have wifi radio range to a couple other hosts.  And that is working well.

We have a couple other small wireless networks in town that I can't reach by radio.  They could be connected to the internet but unfortunately would be behind firewalls that we cannot control.

So till we get things realigned and such, I am looking for examples on how to create a private tunnel from my gateway to those locations.

It doesn't really make sense to put another gateway in the portal, as I doubt the rip packets will pass though.
