Outbound Rules Example - Blocking Instant Messenger

Outbound rules let you prevent users from using applications such as AOL Instant Messenger, Real Audio or other non-essential sites.

If you want to block AOL Instant Messenger usage by employees during working hours, you can create an outbound rule to block that application from any internal IP address to any external address according to the schedule that you have created in the Schedule menu. You can also have the firewall log any attempt to use Instant Messenger during that blocked period.
