Hi!

I don't undertstand how ICQ works behind
natl? How does server send data to 
the client, which is behind a NAT firewall?
As far as i know iCQ uses UDP and does not
keep connection open, so, no soket associated
with the ICQ on NAT or ICQ SERVER. ICQ client
cannot be accessed directly. Then HOW does
a message appear in ICQ when server gets it?
I need to know it because i need to do the same
thing.

Thanks,
Artem
