Here is a comprehensive list of ports that might need to be opened for MP play behind a router. Seems like a lot. Information supplied by Aspyr.

* 6667 (IRC)
* 2033 (Civ4)
* 2056 (Civ4)
* 47624 (Directplay)
* 3783 (Voice Chat Port)

* 28900 (Master Server List Request)
* 29900 (GP Connection Manager)
* 29901 (GP Search Manager)
* 13139 (Custom UDP Pings)
* 6500 (Query Port)
* 6515 (Dplay UDP)

Which of the aforementioned ports are TCP ports, and which are UDP ports? Or should I be opening those numbers in both TCP and UDP?

I was wondering myself if choosing both presents any issues. I would think "both" would work.
