Double NAT question

Networking - AnandTech Forums - forums.anandtech.com
I have at&t dsl at home. It uses at&t supplied wifi router/modem gateway. I have turned off wifi function and am running an asus wifi router from it. The dsl gateway has only 2 ethernet ports whereas my asus has about 5, which I have devices connected to it by wifi and hardwired ethernet. Both are doing routing so I am running a double NAT. I need to open some ports to run my plex media server to the outside. Which I cant seem to do running double NAT. AT&T does not allow you to turn off routing in its gateway, only the wifi function. If I turn off the routing function (bridge mode) on the asus and allow the at&t gateway to do the routing, open the port I need on said at&t gateway, will the devices I have connected by hardwire ethernet and wifi to the asus still be able to connect to the internet? Should this fix my problem with forwarding the port I need, since cant seem to get it to work through double NAT? Thx for any assistance.
