The QoS priority definition for a service determines the queue that is used for its traffic passing
through the FVS124G VPN Firewall as follows:
Example 1 (priority unchanged): If the native ToS setting for a service is 3 and the Netgear QoS
setting for this service is None, then the traffic for this service is placed in the queue that handles
priority 3 traffic. The priority of this service through the FVS124G VPN Firewall has not changed.
Example 2 (priority increased): If the native ToS setting for a service is 3 and the Netgear QoS
setting for this service is 4, then the traffic for this service is placed in the queue that handles
priority 4 traffic rather than the queue that handles priority 3 traffic. The priority of this service
through the FVS124G VPN Firewall has been increased.
Example 3 (priority decreased): If the native ToS setting for a service is 3 and the Netgear QoS
setting for this service is 2, then the traffic for this service is placed in the queue that handles
priority 2 traffic rather than the queue that handles priority 3 traffic. The priority of this service
through the FVS124G VPN Firewall has been decreased.
