Sorry, I can't give you much more than a `me too', but I did do a bit of research: ICQ continues working as before as long as you do not use `send message through server'. I'm not sure wether this is a change in AOL's policy or the servers are just plain overloaded (second might be true, as some messages do get through). Unfortunately, with licq, we can not avoid that, when we sit behind a firewall, and specially if the peer also does. I do not understand the situation fully, but opening udp port 4000 on the firewall is definitively not enough anymore. What does work is SNAT'ting all outgoing connections and assigning a small port range (udp and tcp) to each internal client, such that, say, port range 40070 to 40079 always if DNAT'ted to 192.168.0.15 on incoming connections. At the same time, licq must be configured to accept incoming connections just in this port range. I really dislike this solution, as it's a potential security risk. The real solution would be someone writing an ICQ proxy, but this is said to be a major efford. What I'm not sure is how Windows versions do work, but I did observe very strange attempt when asking the client to automatically determine the proxy configuration: Many ports are checked, notably ftp among them. They do work well with squid, but then, I also observed problems in windows with a restrictive firewall. -- Christoph Simon [EMAIL PROTECTED] --- ^X^C q quit :q ^C end x exit ZZ ^D ? help .
