Step 1, draw a diagram. Routers move packets between networks, so you might need to keep that in mind. What does your routing table look like, do you have a default route? Barring the no shut command, can you ping from the router to your PC's?
Edit: Well, OK. I did CCNA back in 2000, they didn't have PT back then
. So I'm playing with PT, and so far I think it's neat, but still draw out your network by hand. I notice you can't do fun things like NAT or DCHP on the router, but banner works even though it's not listed in the commands. Anyway, my diagram works just using static IPs.
