The idea of port triggering is that it opens the port only when requested by local hosts theoretically allowing multiple hosts to use the same ports.  However, it looks more cumbersome to configure because each local port appears to need a separate configuration instead of a range.  I would try Googling how others have done it as I am sure your situation is not unique with cross platform gaming.

Yeah, but that is a single port.  It gets messy when you have many ports to deal with. But, I do think this will achieve your end goal once properly configured.

Any ideas how to find the "triggering port"??

OK.  Video was really a bust as it did not really address multiple platforms at the same time as it suggested it would.

  @Bozac 

The triggering port is just the internal port.

  @pcuttle 

So like this?

  @pcuttle 

SO does it matter what that port is to trigger with??

  @Bozac 

Should be the port(s) listed in table.

To clearify, if you look back to my screen shot,  I'm trying to make sure I have the right "Triggering port". not "External port".    The ports listed for the game are the "External ones".
