What ports do I gotta forward for W2? Is there anything else I should know about online play?

The "Router Problems" section on Spad's (http://www.spadger.uk.ro/) site should help. Liksi's (http://www.liksi.com/prob.htm) site also has good answers to common problems, as does this (http://forum.team17.co.uk/showpost.php?p=395683&postcount=1) post. There are also a few threads that might help on Des's (http://computerhead.biz/forum/index.php) wonderful site.

If you have a problem that isn't covered by any of the above, post here or at Des's and we'll try to help you out.
