RE: One thing. Did you put that PC into the DMZ?

Thanks for your help.

I did not put it into the DMZ, but I did open the port 3389 for forwarding to the local IP of the PC.
From what I can tell, for remote connections you wouldn't need to use a DMZ, you just forward one port rather than opening them all. I plan to use this long term so I don't just want to leave all my ports open indefinitely.

I am using an Actiontec Q1000 if that helps
