There is varying levels of difficulty when you want to BYO router. The situation for AT&T U-Verse isn't too fun. If you want to use your own hardware, you only have a few options:
1. They offer "IP Passthrough" which is fake Bridge Mode. They still do routing and you'll still hit NAT table limits of 4096. Connection falls apart for anything over 3000.
2. You can dump and reverse the router-gateway firmware and 802.1X/EAP authentication. Oh goodie.
3. There's a history of exploits for the NVG510, NVG589 and NVG599. Try your luck. [1] [2]
4. Create some "magic" to split the 802.1X and untag VLAN0. Works in Linux at least. [3]
5. But good luck if you want to do this in pfSense or FreeBSD. There's an open BTC bounty if you've got any netgraph / networking chops. [4]
