Indicate Which IP Addresses are Behind a Firewall
When an Instant Messaging router receives a message, it determines whether the IP address of the client sending the message is inside or outside the corporate network. If the message originates from a local IP address (that is, from inside the corporate firewall), the server refers the message. If the message originates from the Internet (that is, from outside the corporate firewall), the server sends the message through a gateway.
Note Firewall settings only apply to your company if it is protected by a firewall and you want Instant Messaging connectivity to the Internet. If you are installing a test deployment or an internal-only deployment, no action is necessary.
