Hello, I am desperate. No matter what I do, I cannot get an open NAT type. I've spent over at least 10 hours trying to fix it, i've watched every video and every forum. I currently have a motorola netopia 3347-02 modem/router and a netgear Wnr2000v3. I tried dmz, port forwarding, and opening the nat from my netgear router but nothing happens. When i put my modem into system bridge my internet shuts off and when i pppoe with my router that internet shuts off too. I have heard something on double nat but am not too sure how to deal with that. I am just a man who wants to play Call of duty black ops 2 with an open nat type on ps3. Please help. Thanks.
