FVS338 ProSafe VPN Firewall 50 Reference Manual 
4-2
Firewall Protection and Content Filtering
v1.0, September 2006
Outbound: Allow all access from the LAN side to the outside.
Services-Based Rules
The rules to block traffic are based on the traffic’s category of service.
Inbound Rules (port forwarding). Inbound traffic is normally blocked by the firewall unless 
the traffic is in response to a request from the LAN side. The firewall can be configured to 
allow this otherwise blocked traffic.
Outbound Rules (service blocking). Outbound traffic is normally allowed unless the firewall 
is configured to disallow it.
Customized Services. Additional services can be added to the list of services in the factory 
default list. These added services can then have rules defined for them to either allow or block 
that traffic.
Quality of Service (QoS). Each service at its own native priority that impacts its quality of 
performance and tolerance for jitter or delays. You can change this QoS priority if desired to 
change the traffic mix through the system.
Outbound Rules (Service Blocking)
The FVS338 allows you to block the use of certain Internet services by PCs on your network. This 
is called service blocking or port filtering. 
Note: Se
 for yet another way to block 
outbound traffic from selected PCs that would otherwise be allowed by the 
firewall.
