Setting Quality of Service (QoS) Priorities The Quality of Service (QoS) Priorities setting determines the priority of a service, which in turn, determines the quality of that service for the traffic passing through the firewall. The user can change this priority: • On the Services screen in the Custom Services Table for customized services (see Figure 5-8) [Security > Services]. • On the LAN WAN Outbound Services screen (see Figure 5-2) [Security > Firewall > LAN WAN Rules and click Add to the Outbound Services]. The QoS priority definition for a service determines the queue that is used for the traffic passing through the firewall. A priority is assigned to IP packets using this service. Priorities are defined by the "Type of Service (ToS) in the Internet Protocol Suite" standards, RFC 1349. A ToS priority for traffic passing through the VPN firewall is one of the following: • Normal-Service. No special priority given to the traffic. The IP packets for services with this priority are marked with a ToS value of 0. • Minimize-Cost. Used when data has to be transferred over a link that has a lower "cost". The IP packets for services with this priority are marked with a ToS value of 1. • Maximize-Reliability. Used when data needs to travel to the destination over a reliable link and with little or no retransmission. The IP packets for services with this priority are marked with a ToS value of 2. • Maximize-Throughput. Used when the volume of data transferred during an interval is important even if the latency over the link is high. The IP packets for services with this priority are marked with a ToS value of 4. • Minimize-Delay. Used when the time required (latency) for the packet to reach the destination must be low. The IP packets for services with this priority are marked with a ToS value of 8. 5-16 Firewall Security and Content Filtering v1.0, October 2008
