The DMZ Plus mode doesn't really kill much bandwidth. I get pretty close to 1 Gbit through it. Maybe 960-980 Mbit. Good enough for me. The real problem with the DMZ Plus mode is that it basically sets up a NAT to your router and the state table of the modem is somewhat limited. I've never had any problems but supposedly it might choke if you have tons of open connections.

DMZ plus mode is now where near bringing your own hardware and plugging it into the ONT. Everything still has to go through the AT&T gateway.

Comcast will let you bring your own modem and plug it into the coaxial. I've heard google fiber will let your bring your own stuff.

DMZ plus is much different than setting up an EdgeRouter to forward the authentication to the gateway. You are in much more control of your network if you don't use DMZ plus.
