Firewall Protection and Content Filtering

6-5

•

Quality of service (QoS) priorities—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.

Because the FVS124G 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. 
However, by defining an inbound rule you can make a local server (for example, a web server or 
game server) visible and available to the Internet. The rule tells the firewall to direct inbound 
traffic for a particular service to one local server based on the destination port number. This is also 
known as port forwarding. 

See 

 for yet another way to allow certain types of 

inbound traffic that would otherwise be blocked by the firewall.
