Bridging

There is no true bridge mode on the 2Wire CPE gateways, however you can still configure them such that almost all functions of your own router will work properly.

1. Set your router's WAN interface to get an IP address via DHCP.
   This is required for the modem to recognize your router.
2. Go to Settings → Firewall → Advanced Configuration.
3. Confirm that the following options are unchecked:
   • Stealth Mode
   • Block Ping
   • Strict UDP Session Control
4. Enable every option in the Outbound Protocol Control section except NetBIOS.
5. Disable NetBIOS in the Inbound Protocol Control section.
6. Disable all seven options in the Attack Detection section.
7. Click the Save button.
8. Use a working Ethernet cable to connect your router's WAN interface to one of the 2Wire's LAN interfaces.
9. Restart your router and wait for it to receive an IP address assignment from the gateway via DHCP.
10. Log into the 2Wire router's web interface and navigate to Settings → Firewall → Applications, Pinholes, and DMZ.
11. Select the entry for your router under section (1).
12. Click the DMZPlus button under section (2).
13. Click the Save button.
14. DO NOT reboot the modem as the settings will go all wonky and you will have to start the process over from the beginning.
15. Reboot your router or renew its WAN address lease from its web configuration page. The router's IP address should now be the public IP address allocated for the 2Wire gateway.
