Firewall Settings Requirements:
For ICQ to successfully work behind a firewall the following system configurations must be set by the System Administrator for the systems network.
Client to server Communication:
This is done via port 5190 TCP to login.icq.com (please note- allow a bi-directional connection to the port for login.icq.com and not any specific IP address, since it stands for more than one IP address).
How do i do this?Open a port range?UpnP Forward?
