Outbound Rule Example: Blocking Instant Messenger
Outbound rules let you prevent users from using applications such as 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.
.
Inbound Rules (Port Forwarding)
Because the DGFV338 uses Network Address Translation (NAT), your network presents only one 
IP address to the Internet and outside users cannot directly address any of your local computers.
