Of course, you can update the firmware and put the 2Wire in bridge mode (explained before) but, if you are in the same situation that I am, you will not be able to update the firmware of your 2Wire because it's password protected and I was not able to update it.
Here are the two solutions that worked for me (both testes successfully):
1) Put your Airport Extreme in bridge mode (explained in a previous post)
2) Change the configuration of your 2Wire without flashing it by following these procedure :

- Connect White 2Wire Modem/Wireless Router to phone line, make sure DSL light is on.
- Connect computer to any LAN port of 2Wire Modem/Wireless Router.
- Use Internet Explorer, Google Chrome, Mozilla Firefox or any other browser to access 2Wire Modem/Wireless Router's web based interface. Default IP address may be 192.168.2.1.
- Ensure 2Wire 2701HG modem cannot make PPPoE connection - Use INCORRECT Username and/or Password for PPPoE connection settings. Internet Connection --> Advanced Settings.
- Disable DHCP Server on White 2Wire Modem/Router. Local or Home Network --> Advanced Settings.
- Disable Wireless on 2Wire 2701HG - it is useless now and will not work anyway. Local or Home Network --> Wireless --> Disable.
- Disable Firewall on 2Wire 2701HG Modem/ Wireless Router. Application Support --> Advanced Settings --> uncheck Stealth Mode and Block Ping. Save Settings.
Now White Modem/Wireless Router 2Wire 2701HG is working in Bridge Mode.
Disconnect computer from 2Wire Modem/Router.
- Existing Internal Router needs to be connected using it's WAN port to any 2 Wire's LAN port (any one 1-2-3 or 4 , but use just one).
- Setup Internal router to dial PPPoE connection using RIGHT Bell Username and Password.
In conclusion, i'm not really sure which one is better and I didn't see any performance difference between those two but I don't know if there is a security issue with these solutions.
