static routing with cisco routers

You have to adjust your cisco due to manual.

Using HyperTerminal for windows either minicom for linux send to cisco appropriate script commands (in case your cisco has not yet IP address so you need make initial connection through com port). As rule cisco has factory IP (if someone didn't destroyed it yet) so you can communicate with it by means telnet or ssh protocol to send its script commands. Like ->show running-config

As I could understand you have here three network interfaces to be done. Just read manual throughly and do your work.

If your cisco has web-interface for its adjusting --- you're lucky guy, though it's not safely for security matter, but easy to use.

I think it would be more suitable for you to visit cisco site either cisco devoted forums.

Good luck.
