DG834G Reference Manual Outbound Rules (Service Blocking) The DG834G allows you to block the use of certain Internet services by computers on your network. This is called service blocking or port filtering. You can define an outbound rule to block Internet access from a local computer based on: • IP address of the local computer (source address) • IP address of the Internet site being contacted (destination address) • Time of day • Type of service being requested (service port number) Following is an application example of outbound rules: Outbound Rule Example: Blocking Instant Messenger If you want to block 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 ADSL modem router log any attempt to use Instant Messenger during that blocked period. Figure 5-7 5-10 v3.0, September 2005 Protecting Your Network
