This is more an answer to the ICQ part of your question, but instead of
playing firewall footsy with ICQ to get licq running, I simply use the
ip_masq_icq module available at 

http://members.nbci.com/_XMCM/djsf/masq-icq/index.html

It's nice because you don't have to open ports on your firewall, and it
allows multiple ICQ clients behind the firewall to use ICQ (great for
masqing a bunch of roommates behind DSL), instead of just one ICQ client
with the firewall solution. Also, the module supports chat and file
upload/download whereas the firewall solution doesn't, I think.

Later,
Paul
