Admittedly it's been a while since I have had U-Verse, but I was able to disable wifi on the modem, put the modem in "DMZ mode," and make an Apple Airport Extreme work well with it. Still not real bridged mode, although the router behind the U-Verse modem in DMZ mode would get the real external IP address handed to it so it doesn't act like a double-NAT situation.
You still had to have your TVs run through to the actual U-Verse modem, though, and can't plug them into a router sitting behind it.
- coin 13y agoWhat's wrong with double NAT?

Nothing really, but you should generally avoid it if possible. It just creates the possibility of having unexpected problems later on.
- crummy 13y agoDouble port forwarding, for one.
- chomp 13y ago> You still had to have your TVs run through to the actual U-Verse modem, though, and can't plug them into a router sitting behind it. Yeah you can. I have Uverse Router ==> PFSense Box ==> GigE switch ==> Uverse TV box. The trick is enabling IGMP proxy. The first 10 seconds of a Uverse TV stream is transmitted over UDP. After 10 seconds, it switches to multicast. You need IGMP proxy on the PFSense box (or IGMP proxy capable switch) to relay that multicast traffic to the ports on the other interface. After that, DMZ your PFSense box, add just a few firewall allow rules, and you're done!
- ben1040 13y agoAh, that's right, now you're jogging my memory as to why it didn't work for me. My consumer level router I had at the time wasn't capable of doing the IGMP proxy. Out of curiosity I looked and my Asus RT-N66U does in fact offer it, so more consumer routers may be directly compatible now too.

- chomp 13y agoYeah like tacoman said, it's for channel changing. Multicast saves on bandwidth.
- tacoman 13y agoIt's how they deliver instant channel change. The unicast udp burst is about 30% higher than the nominal bitrate of the multicast. The STB stitches the unicast and multicast together seamlessly.
- hahainternet 13y agoThat is an impressively smart solution really. I don't have instant channel change :(
