DMZ Mode on Airport Extreme?

[unstoppablekem]

I have TWC internet and have a few Airport routers. For gaming reasons I need to put my router/s into DMZ mode. How do I do that, can't seem to find it. Thanks.

I had to do this for my son:

Go to Network > Network Options and make sure your have Allow Teredo tunnels checked. Make sure to save your changes.
