  1. Look into Port Forwarding. You'll need to identify the port being used for the connection and then forward that port to the private IP of the computer.

    You could also put the IP address of the computer into the DMZ and set port forwarding of all ranges to that IP address.
  2. IIRC, the DMZ does not block any ports. It's wide open to the internet by default.
    But that could change between routers I guess.
  3. You are correct. Kind of added in a little trick that if it wasn't in the DMZ the port forwarding part would still make it work. Just wasn't letting in on that one. :)
