I'm using the MI424-WR Rev D, and I figured out how to do the Port Forwarding fairly easily. Me and my gf play Black Ops 2 for PC, and we BOTH need port 3074 opened since our NAT was showing moderate. After I put in mine, my NAT switched to Open like it should. However, when I go in the router and specify the same port for her IP Address, it errors out with a conflict saying the port is already opened for another application. Is there no way for me to assign the port to multiple IP Addresses? Any other router I've used in the past let the IP be the unique identifier, not the port number.
Also, I tried the DMZ Host for her address but it did not fix her NAT issue.
