Port Forwarding through WN3500RP

I have a security camera on the far corner of my house that was not connecting in well with the AT&T 2Wire router. So I bought the Netgear WN3500rp and set it up to connect to my 2wire router. I can access the camera feed via the extender without any issue, but the problem is that the port forwarding doesn't seem to be working. When I go under the firewall setting, The IP address is just 0.0.0.0 and I set it up the same way I set up all the other cameras on the 2wire router to do port forwarding. If I set the camera to access the 2wire router directly, the port fowarding works and I can access it via the external IP address. The question is how do I get the portforwarding to work when the camera is connected via the extender. Thoughts?
