I'm brand new at this but have managed to get my Ubuntu Debian box routing for my home LAN. The point for me was to replace my little blue Linksys router, and it's working fine so far. About all I had to do was apt-get install ipmasq and dnsmasq. There's a feature on the Linksys box, however, that I can't figure out how to implement, because I don't know how it worked on the Linksys box, and that is the DMZ function. When a machine behind the router was going to serve as a, for example, game server (like Unreal Tournament 2004), the only way I could get it to work was to put that particular IP on the DMZ, which, I gather, meant that it looked like it was right on the net, unprotected, unrouted, unmasqed, et cetera. Since I'm trying to understand what the Linksys box did and give the new router box the same abilities, it would help if I knew what the heck that feature was really called, and/or how to implement that in iptables. Looking through the archives I see a lot of Linksys-related questions; please forgive yet another one. david williamson
