I had that problem too
LOL I had that problem too years ago. I just set the ports to "0.0.0.0" so it would auto-detect any available open port. MRO used to use "6500", then it changed to "6666", now I'm not sure what the default port is set to as I still use "0.0.0.0".
Also if you're on a "shared" network, I don't think you can host / server races, but I'm pretty sure you can join / client the races.
(sorry for late reply, I didn't see the post till now.)
