Thanks for the response Kramerika
I didn't have 27900 open so I opened it up and will try again tonight.
I'm also a little confused with the trigger portion of my router setup. It is supposed to open up a port more multiple connections. Not sure though what the "trigger" (1 port) should be and what the "public" ports should be (range of ports).
Right now I have opened up a number of ports in my virtual server/port forwarding section of my router.
