• Local computers must access the local server using the computer’s local LAN address
(192.168.0.11 in the example in
Figure 6-12 above). Attempts by local computers to access the
server using the external WAN IP address will fail.
Outbound Rules (Service Blocking)
The DG632 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)
• Type of service being requested (service port number)
Following is an application example of outbound rules:
Outbound Rule Example: Doom
If you want to block usage of the game Doom, you can create an outbound rule to block that
application from any internal IP address.
