• 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.

Inbound Rules (Port Forwarding)

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.

Note: See “Port Triggering” on page 6-28 for yet another way to allow certain types of

inbound traffic that would otherwise be blocked by the firewall.
