In reply to Brian. You can do router to router and in effect turn the AT&T router's network into a DMZ, which is certainly useful in some applications. Bridging is useful in others, like if you want to set up failover with a second ISP, or combine two ISP connections for more bandwidth. I had trouble doing router to router in either of those applications.

I have to correct a mistake in my first post. DHCP is not disabled on the U-verse router. However, the U-verse router recognizes the static IP from my router so there would not be a conflict of two clients with the same IP. Not that there are any other devices on that subnet. Sorry about the mistake, it has been a few years since I set this up.

When you have your own router, why bridge? Why not router to router? I have AT&T U-verse. My own router is set up with a static IP on the WAN side in the same subnet as the U-verse router and the rest of my home network are on other subnets. The U-verse router is set up for static address assignment with no DHCP. I did get a warning from the U-verse router that a third-party router was detected and it provided instructions for setting up DMZ plus. The warning stated that there could otherwise be instability. But with DHCP disabled on the U-verse router, with a static connection between the two routers, and the rest of the network on other subnets, I don’t see how. My reason for setting things up this way is to provide an extra layer of security.
