I too am looking to set up a Pitboss game using vanilla Civ IV (no expansions). I have downloaded the Pitboss application
http://www.2kgames.com/civ4/downloads.htm
I have opened up the Pitboss.exe and went through the steps in setting up the game except the SMTP email I left blank since I dont know how to configure that. Then I launched the game and a new window popped up.
Now I cannot figure out how I can get into the game to choose my civ and start playing! Nor do I know how to get others to join the game....uh oh I just did another online google query asking "what is my IP" and now the number is different from yesterday...To fix this I heard I need a dynamic dns as well as open "ports" to my router. I use a qwest dsl modem box I guess that is my router. But How do I "open ports" and which ones?
Help!
