Best UVerse Modem for Bridging

I have UVerse Internet only, no TV nor phone. I need a modem that can do true bridging. I have fought with the NVG510 for several days. I wasn't able to get it to forward a part to an internal PC so I bought a Linksys last night. The 510 will forward all traffic to the Linksys but it's still doing NAT. I need it to pass through directly to the Linksys exposing the public facing IP to the Internet port on the Linksys. What alternative modem can do this? My ultimate goal for now is to forward 443 to a host inside my network. The next phase of this will be running Microsoft Direct Access to the network in my home.
