Sean,

I had att u-verse up until a week ago and loved it. Ran Asterisk behind it with great success. (I only left u-verse because of a physical move).

Anyway, by default the u-verse router simply will block upd like noone's business. Make sure you have a firewall and then tell the u-verse router to open everything to that firewall (and proceed like you did on dsl). If you change the mac of your firewall, you'll need to reauth it again.
