These are the instructions on how to configure a U-verse gateway to send all of its incoming traffic to your own router without impacting its normal networking services. i.e: Using it as a modem only.
The gateway can be accessed through IP address 192.168.1.254. The gateway will on occasion prompt for the password labeled "system password" This is found on the serial number sticker on the router.
Turning on DMZplus:
All traffic needs to be forwarded to the third party router. This can be done as follows:
- From the gateway, navigate to: Settings---->Firewall---->Applications, Pinholes and DMZ. this will bring up a list of computers connected to the 2wire and a list of applications which use port forwarding
- Choose the router from the list. It appears as a link named "choose <name>."
- Change the settings to "Allow all applications (DMZplus mode)."
Assigning a public IP:
The third party router needs to receive a "Public" IP address. The router needs to acknowledge that it is a public-facing device. UPnP and NAT-PMP rely on determining the public IP, and having the correct WAN IP is required for many routers.
This can be achieved by assigning the router the public IP address as follows (options may vary depending on router):
- Navigate to Settings---->LAN---->IP Address Allocation.
- Locate the settings box for the router.
- Change its "Address Assignment" from "Private" to Public."
After the router renews its DHCP lease, it assigns the public IP address.
