[quote]If you use more than one console on the same network, you can't use port forwarding (thank Jeebus!!!), you will need to use uPnP instead. Mainly it does the same job as port forwarding, but it can send the same port to multiple devices, automatically.[/quote] I believe you can as long as they aren't online at the same time since the ports used are the traffic ports used for nearly all online gaming. Albeit some are specific to console/game. I have my XB1 port forwarded and it doesn't affect my Wii U since the 2 aren't in use at the same time, my XB1 does however also have a static IP, which is well worth looking into and not difficult for a novice to setup.
