I don't know if you can limit ICQ to just chat...I'd write to their Tech
Support to find out. More information on how to configure your firewall
can be found at:
http://www.icq.com/firewall/netadmin.html
This is what they have to say on client to client connections:
"Client to client connection is done using the TCP protocol, using port
range 1024 - 65535. this means that the client needs an open listening port
within the mentioned range - 1024 to 65535."
Sounds like a lot of ports to me for something that is the functional
equivalent of email.
