That's certainly true but these problems seem to be a direct result of going
through STN. If I drop off STN and connect directly to my ISP, the problems
automagically go away.
Is it best to leave a range of 12-24 ports open for ICQ as in the FAQ or a
whole mess of 'em? I also would like to know what would be the difference
(security - wise) between the way I normally connect to the net (via dialup
ISP) and using STN with all ports open ... 0 - 64k or so for TCP/IP and UDP.

Right - if you don't disconnect from ICQ and instead just click off the net,
ICQ doesn't notice you're disconnected. Then when you connect to your other
ISP, or even the same ISP again, and try to connect, ICQ says - "wait, he's
already connected at that UIN - can't have two people on the same UIN with
different IPs - he'll have to wait..." until the original UIN times out.
The ICQ client sends something along the lines of a ping or keepalive
ack/nack thing to the server every so often. You can see this very clearly
with the Linux variant called LICQ. It has a nifty little network traffic
window :)
If anyone has gotten ICQ to work flawlessly (particularly if they have a lot
of active users on their ICQ list) I'd sure like to know about their setup
both for STN and ICQ's firewall settings.
