Yeah, that's pretty much it. NAT isn't involved, so that's not a 
problem, but if there are random UDP ports chosen for communication by 
the server after the initial connection is made, I guess I'm screwed :-/

Btw, I'd like to say sorry for screw-up with the date in the last mail, 
it just that I'm so blazingly fast I'm one day ahead of everyone else. 
OK, not really. But, in all seriousness, I was born two weeks early, so 
being just one day ahead is actually an achievement extraordinaire :-P

Cheers
