I have set up one desktop to listen on port 3389 so we can remote into it.
I have it forwarded on the router.
Now I want to do the same thing on another desktop using port 3390. I have it configured the exact same way but when I try to console in from the outside it does not work. I used the ip x.x.x.x:3390. Just in case someone asks. The network is using a Small Business Server. I was told that SBS does not support port forwarding. It only works for the default 3389 port. Which does not make sense.
