Configuring Other Network Components

The purpose of configuring other network components for instant messaging filtering is to redirect the instant messaging traffic that is going on between clients and servers to an appliance that has one or more instant messaging proxies running.

For example, under the ICQ protocol, clients send their requests to a server with the host name api.icq.net. For instant messaging filtering, you need to create a DNS redirecting rule that lets this host name be resolved not to the IP address of the ICQ server, but to that of the appliance.

In a similar way, firewall rules can be created to direct instant messaging traffic to an appliance rather than to an instant messaging server.
