For att dsl, you can change the ip, and there is a tutorial on here for doing so. if you have the all-in-one residential gateway used for att uverse, you can not change it. if I'm wrong, please do tell. i loveed their tv service, but need the ability to change the ip freely sa you do. I've worked at att, know people at att, and have talked to a half dozen att techs, all say the system is designed to lock down the ip address because the tv runs off the ip address. if you change the ip address, you lose tv connection, and have to call in to have it reset.
You can argue all you want, but changing the ip on that box is a lost cause.
