Outbound Rules (Service Blocking)
The FVS318v3 allows you to block the use of certain Internet services by PCs on your network.
This is called service blocking or port filtering. You can define an outbound rule to block Internet
access from a local PC based on:
• IP address of the local PC (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 an outbound rule:
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
firewall log any attempt to use Instant Messenger during that blocked period.
