All consoles (Wii, Xbox 360, PS3, Xbox One, PS4, Wii U) and many PC games use port 3074/udp, but they also keep a list of alternate ports that they will try. And because it's an active thing for the client to do, it can try several different ports. Rather than relying on a third party triggering a port, the client machine that needs to be forwarded makes the request. UPnP gets around this because it's (sort of) stateful. So you could theoretically have two consoles with Open NAT on the same network, but not simultaneously. Where port triggering is technically better than a static forward mapping is the ability to have multiple triggers (trigger X forwards Y to Z, but trigger Q forwards Y to R). And of course you can only forward that port to one machine at a time. Since Xbox games have no concept of port triggering, the port must be 3074/udp for both triggering and forwarding. It basically tells the router, "If someone externally pings port X, forward port Y to client Z." (X and Y can be the same or different ports). The only thing that will help you is a router with both a functioning UPnP IGD server and support for NAT loopback.
