Re: Sliding port NATs

More generally, there are still buggy routers in existence that may 
re-allocate a UDP port every once in a while -- there are still routers 
in the wild that re-set themselves from scratch once an hour or 
something mad like that, and re-establish all session state after re-set.

Of course, there are also games that will kick you if you drop a single 
UDP packet. My kids have to run a wire across the living room floor to 
play ToonTown Online, because the wireless in my house is not reliable 
enough, and they'll get kicked every 3 minutes otherwise...

Do you ever have more than 255 players in a game, though?

Sincerely,

jw
