Assuming the information at http://www.icq.com/icqtour/firewall/netadmin.html and http://www.icq.com/icqtour/firewall/#configure is accurate, you need to do the following: - On the box running NAT, you need to start natd with the following flag: redirect_port tcp <icqhost>:<someport> <someport> where <icqhost> is the machine running icq and <someport> is some port between 1024 and 65535. I'd suggest -not- using 1080, 31337, 27374, or 12345 for these, unless you want to show up in script kiddie scans. - On the box running icq, there should be some sort of firewall setup screen. Choose the option, "I have no Socks.x Proxy server but I have a range of listening ports I can use." and insert the value of <someport> there. Do note that this will mean that someone attempting to connect to TCP <someport> on the firewall will be forwarded to the machine whether it's an ICQ connection or not, and also that this is completely off-topic for -stable - I'm sure Mirabilis has help forums for exactly this sort of question.
