Att router configuration
The Firewall | IP Passthrough tab was, obviously, the most important page in this process. I also turned off all of the “advanced filters” on the Firewall | Firewall Advanced tab. This is what it looked like when I was done:
ATT ROUTER CONFIGURATION PRO
I wanted the UDM Pro to provide all of the firewall filtering, so I disabled the filters on the Firewall | Packet Filter tab. What worked for me was to leave DHCP enabled, Public Subnet off, and Cascaded Router off.

But I still got a few things wrong along the way, so I thought I’d document what my BGW210-700 configuration looked like when I finally got my UDM Pro assigned the public WAN IP address. I found Reddit posts and Help/Support pages that got me most of the way there. The closest it comes to a bridge mode is its “IP Passthrough” mode. My research indicated that I’d want to enable “bridge mode” on my router, but it turns out the BGW210-700 doesn’t have support for a true bridge mode *. Unfortunately, some research showed that I couldn’t drop the AT&T router entirely it was providing the authentication for my internet service. With the UDM Pro, I had a real gateway, and I no longer needed my AT&T BGW210-700 gateway/router to handle any of the services it was previously performing. While there’s no question the Unifi Dream Machine Pro is overkill for a home network, it was just the combination of power, control, and convenience I’d been looking for.

I’ve long wanted to have more control/flexibility in my home network, and 2020 finally gave me the justification to make some upgrades.
