There are 2 Windows machines behind the NAT running ICQ clients. People on my ICQ list see me come on and offline quite often. So I'm assuming that I am having problems sustaining a connection with the ICQ server, or the ICQ server is trying to send me a reply packet and it cant get through the firewall on 4000. I have no problems sending and receiving ICQ messages since the firewall option I have enabled is open. It has no problems punching out a TCP port to establish a connection. However I am seeing in my logs that there are UDP connections coming from the 205.188.153.* and 205.188.179.* via port 4000. I've used the this to try and rectify this. "ipfw add 00110 allow udp from 205.188.0.0/16 to 4000 in" and "ipfw add 0010 allow udp from 205.188.153.0/24 to 4000 in" However, I still see connection ateempts UDP connections destined to port 4000 from the above subnets. if anybody can shed some light on this, I would appreciate your help Thanks, Ben.
