I have two identical devices plugged into the back of my Dir-655. each has it's own individual IP address but both are trying to communicate on the same ports and it's causing problems. I was told that I needed to assign each device to certain ports in the router. I tried port forwarding but that didn't work and I was told that isn't what I need to do anyways. can someone tell me how to assign certain ports for communication to certain devices? I've searched high and low and I'm totally lost lol thanks for your help
