How to Configure 2wire 3800hgv-b bridge mode

Step 1:
On the 3800hgv-b device:

http://192.168.1.254 (default router IP. We will change the IP to 192.168.0.1 later.)
http://192.168.0.1 (have changed to this IP)

1. Go to Settings -> LAN -> DHCP

2. Check the following:

DHCP Network Range = 192.168.1.0 / 255.255.255.0 (default)
IP Address Allocation Start: 192.168.0.64
IP Address Allocation End: 192.168.0.253

3. 3800hgv-b device will reboot.

4. After reboot, if your computer’s IP is not changed, run ipconfig /release and ipconfig /nenew to refresh your computer’s IP.
5. Go to Settings -> LAN -> Wireless
6. Check the following:

Wireless Interface = Disabled
SSID Broadcast = Disabled

7. Go to Settings -> Firewall -> Applications, Pinholes and DMZ

8. Click the Save button.

9. Manually reboot router, so the router will refresh its WAN IP (getting a DMZ public IP from the AT&T modem).

10. After router is rebooted, verify the following information (can’t change, just verify):

IP Address Allocation:

Device Status = DMZ Device
Firewall = Disabled
Address Assignment = Public (Select WAN IP Mapping)
WAN IP Mapping = Router WAN IP Address (default)
Cascaded Router = No

System Info -> Event Notifications:

Router-Behind-Router Detection = checked

Step 2:
On the new router:

LAN Setup:

Router IP: 192.168.0.1 (make sure you use different subnet than the 3800hgv-b’s subnet)
Subnet Mask: 255.255.255.0
DHCP IP Range: 100 – 199
DHCP Reservation: varsity 192.168.0.110 00:1c:c0:4b:74:e8

Wireless Setup:

SSID: 2WIRE124
WPA/WPA2
Network Key: 5218430569

/*
set up a static route:
Interface Destination Subnet Mask Gateway
WAN 192.168.1.254 255.255.255.254 192.168.1.1
*/

Step 3:

1. Open a web browser, browse any web page.
2. The system is going to present you with a page that says “router behind router” is detected.
3. Click Disable to confirm the “router behind router” configuration.
