Cisco 2500 Series routers behind IPCop Router Issues...

I have a stack of four Cisco 2500 series (two 2501's and two 2514's) routers that I bought for use with the CCNA courses. I have the four configured properly to where a connected workstation (with a static IP) can ping all the way out to the last Cisco router but after that hop, I can get no where. When I do a trace to any IP past the last Cisco router, it times out each time. What is strange is that when I'm in Hyperterminal connected to one of the Cisco routers, I can ping ANY website or any ip on my network and they are all successful.
My question is, do I need to setup a static route in IPCop and if so, how do I go about doing this? Or is it something to do with my Cisco router configs or the workstation config?
But I would still think that it wouldn't matter to IPCop as long as it knows where to send the packets/frames. E0 on the last 2500 router is a static ip that's in the same subnet as the primary IPCop router. My Cisco router config is posted below (the configs are basically the same on all four Cisco's except for the RIP network statements, hostname, and interface IP's of course)

Thanks for any help guys!
