You can't ``fix'' problematic configurations at the router end, usually, but that's what DHCP is for. :-) > Basically i have a hotel and would like to install a system that would > let guests use their own laptops in their rooms to connect to the > internet via a T-1.

The problem is distinguishing real internet addresses from misconfig'd laptops. If I telnet to 128.223.200.2 and there happens to be a laptop on the local net with that number, how do you know whether I want the local net one or the one in my office across the country?
