I'm experimenting at home with hardware. I'm playing with low end T1 equipment at the moment. What is a low-cost router solution to hook to a CSU/DSU? (where I don't have to pay a ridiculous $800+ IOS relicensing fee preferably.) With Cisco 2500's going on Ebay for $10-$30, I'd like to find something in the <$50 price range that will do basic routing and has an RJ45 connector plus some serial way for me to hook the CSU/DSU in to it. Bonus abilities would be built in DHCP, NAT, 1-1 NAT mapping, port mapping, and basic firewalling. Maybe I'm looking at this too hard. Is there a cheap Smart-Jack to Ethernet conversion system out there I'm missing for small businesses? I know the hardware has been around for a while and the software I'm looking for is not complicated. Maybe someone knows of a different OS that'll go on the cheap cisco routers like: http://www.mcvax.org/~koen/uClinux-cisco2500/images/ ...only with a heartbeat. (That's not going to stop me from downloading it and trying it though.) Thanks for any suggestions on or off list. Gerald
