ICQProxy

This software works as a proxy-server.
The simple way to use this software in the local network is to create a Forward Lookup Zone on the local DNS-server for "login.icq.com"
You can change ICQ-server name to the address of the computer (or DNS name) where the software is located.
It is recommended to use access-list (Main menu -> Options -> Access list) to restrict access to the proxy-server.
