Putting the 2Wire 3801HGV (AT&T UVerse) into Bridge (Passthrough) Mode

If you have a NAT enabled router or firewall behind a 2Wire 3801HGV, and you want the router/firewall to have a public IP address, then this is how you can enable Bridge mode (aka Passthrough mode):


Log into the router (http://192.168.1.254) using the system password from the sticker on the side of your UVerse gateway.

Click Settings, then Event Notifications
Check the box labeled "Router behind Router"
Save this.

Attempt to browse to any webpage. The UVerse gateway will intercept the connection and display a page that says that it has detected a router behind router condition, and ask if you want to configure for that.

Answer yes, and it will prompt you for your system password. Type the password in, and you're good to go!

Note:   You may need to reboot your router/firewall so it will get its new public IP via DHCP, and you should assign an IP Address in the 192.168.1.0/24 subnet to your router's external interface so you can still reach the UVerse gateway to configure it later.


Hope this saves someone some headaches!
