Re: U-verse for BUSINESS? : 2Wire 3600HGV bridge mode? or another AT&T supported VDSL modem?

Thanks for the help in this thread -- I've been troubleshooting some issues and your comments have been invaluable.
I do have a question, though. I followed the instructions in post 2 on this thread (turning the 2Wire into a pseudo-bridge) and have a Netgear WNR2000v3 in the DMZ, with all my other devices hanging off the Netgear (had to do this because my wife works from home and has a SIP phone that connects to an IP PBX at her work that I simply could not get to play nice with the 2Wire, even in the DMZ).
I think I ran into the problem you mention in point 8 of that post, wherein after a short period of time the Netgear would just lose its Internet connectivity; I guess it was probably blocking the DHCP renewal packets. I followed your advice and set the IP address static and everything has been fine for 30 minutes now. Hooray!
My question is this: since the IP address I've set the Netgear to is actually the public IP address the 2Wire is assigned by AT&T, and it's not a static address, is that address likely to change regularly? I assume when that happens, my connectivity will break pretty hard. Do I need to get a static IP from AT&T? Do they even offer those to residential customers?
