Router Behind Router Detected

If the gateway detects the presence of a third-party router, the Router Behind Router error page displays. If 

a third-party router is connected to the 2Wire gateway, network instability can result because both devices 

are trying to manage private IPs via NAT.

The best solution is to remove the third-party router from your LAN since the 2Wire gateway can manage 

your home network. If this option is not acceptable, move the third-party router to DMZPlus Mode by clicking 

the 

Resolve

 button..

Provision Gateway

This error message is displayed if you attempt to access 

the Internet before configuring your gateway with the 

correct PPP credentials (username and password). Click 

the 

Set Up Now

 button to enter the PPP username and 

password provided to you by your service provider. After 

you have completed this process, you should be able to 

access the Internet.

Note: 

DMZplus is a special firewall mode that is used for hosting applications. When in 

DMZplus mode, the designated computer shares your gateway’s IP address (Router 

Address), appears as if it is directly connected to the Internet, has all of the unassigned TCP 

and UDP ports opened and pointed to it, and can receive unsolicited network traffic from the 

Internet. Because all filtered traffic is forwarded to the designated computer, DMZplus mode 

should be used with caution. A computer in DMZplus mode is less secure because all 

available ports are open and all incoming Internet traffic is directed to this computer.
