Set up Linksys E4200 router behind my AT&T U-verse Residential Gateway (2-Wire)

Set up Linksys E4200 router behind my AT&T U-verse Residential Gateway (2-Wire)

I want to set up my Linksys E4200 router behind my AT&T U-verse Residential Gateway (2-Wire). Essentially disabling the WiFi on the Residential Gateway and making the E4200 handle all routing and WiFi for my network.

 

What steps do I take for both the Residential Gateway (2-Wire) and the Linksys E4200 router to accomplish this?

 

P.S. I am getting U-Verse TV, Internet and Voice installed this Friday 11/30/2012

See the following post for instructions to set up your own router using the DMZPlus feature:

Thanks for the quick reply Dan! I actually had that bookmarked for reference already.  

 

Hopefully those steps work.  I will post results on Friday!

SomeJoe7777,

What are the reasons for doing the following steps?

10. Uncheck the following: Stealth Mode, Block Ping, Strict UDP Session Control.
11. Check everything under Outbound Protocol Control except NetBIOS.
12. Uncheck NetBIOS under Inbound Protocol Control.
13. Uncheck all the Attack Detection checkboxes (7 of them).

Setting those options as specified makes the 2Wire as transparent as possible, such that it minimally interferes with your traffic. I specified these settings because the goal is to make the 2Wire as much of a transparent bridge as it can be.

Security is left up to your router and its firewall.

Alright I will implement those on the RG then.

Do I need to manually change the IP address of the router at all during the setup?

I have read about changing it from 192.168.1.1 to 192.168.2.*

Yes, you need to make your router's LAN subnet different from the RG's subnet. The RG's default subnet is 192.168.1.x, so if you leave the RG's set like that, you need to make your router's LAN subnet something different, like 192.168.2.x.

Ok, thank you

So the RG LAN will be at 192.168.1.254 and the router LAN will be at 192.168.2.1.

Also, does the Subnet Mask of the router (255.255.255.0) need to be changed at all?

No, no change in subnet mask.

Line 2 looks like it has a lot of issues.

 

If you're having problems with your service, you should call technical support, have them send a premises tech to your house to check the line. He may need to open a helper ticket with the Installation and Maintenance group (I&M), which are the linesmen, to perform additional troubleshooting.
