FVS338 ProSafe VPN Firewall 50 Reference Manual
•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.
