Quality of Service 81 Quality of Service The QoS (Quality of Service) function allows you to differentiate your network traffic and provide it with high-priority forwarding service. The bandwidth gap between LAN and WAN may significantly degrade performance of critical network applications, such as VoIP, gaming, and VPN. This QoS function allows you to classify traffic of applications and provides them with differentiated services (Diffserv). Figure 67 QoS Settings Screen QoS Settings Define the minimum percentage of bandwidth for each type of traffic. Traffic Mapping You can define up to 16 rules to classify traffic into Diffserv forwarding groups and outgoing VCs in this screen.

This function should only be disabled by advanced users, and if your ISP assigns you multiple IP addresses or you need NAT disabled for an advanced system configuration. If you have a single IP address and 84 CHAPTER 5: CONFIGURING THE ROUTER you turn NAT off, the computers on your network will not be able to access the Internet.
