Let me first admit that I do not know very much about home networking. I've been using Apple Airports for a while, but that is as deep as my knowledge on the subject goes. So here's what I'm trying to achieve: I have a 3800HGV-B Gateway provided from AT&T which only has 10/100 ethernet. I would like to connect my Airport Extreme base station to this with an external USB hard drive to this for time machine backups and eventually a Drobo w/ a Droboshare for all my itunes, movies, etc. How can I do this to take full advantage of the gigabit ethernet on the AE without screwing up my Uverse? I heard something about a DMZ, but i don't know what that is or how to do it. PLEASE HELP!!! Thanks.
