Given that my ISP has agreed to let me tunnel my /24 to his network over my cable modem, I need a way to set up a route tunnel between my Linux box (RH 5.2 kernel 2.0.36) and his Cisco (4500 IOS 11.1(5))
I know Linux has tunnels, but I don't know if they can tunnel with a tunnel peer that is the Cisco itself. If they can, how? If not, what software solutions do I have?
He wants to use a Cisco as it is just something that sits inthe rack and won't require tending. I don't really want to go buy a Cisco 1605-R for each remote site.
I also know that, yes, kernel 2.1.70+ have the GRE code, but I can't find the "rest" of it to set things up.
How can I get this Cisco-capable IP tunnel up and running between my Linux and his Cisco?
