Using QoS to Shift the Traffic Mix
The QoS priority settings determine the priority and, in turn, the quality of service for the traffic
passing through the VPN firewall. The QoS is set individually for each service.
• You can accept the default priority defined by the service itself by not changing its QoS
setting.
• You can change the priority to a higher or lower value than its default setting to give the
service higher or lower priority than it otherwise would have.
The QoS priority settings conform to the IEEE 802.1D-1998 (formerly 802.1p) standard for class
of service tag.
You will not change the WAN bandwidth used by changing any QoS priority settings. But you will
change the mix of traffic through the WAN ports by granting some services a higher priority than
others. The quality of a service is impacted by its QoS setting, however.
See “Specifying Quality of Service (QoS) Priorities” on page 4-22 for the procedure on how to use
this feature.
Tools for Traffic Management
The VPN firewall includes several tools that can be used to monitor the traffic conditions and
control who has access to the Internet and the types of traffic they are allowed to have. See
“Viewing the Router Configuration and System Status” on page 6-30 for a discussion of the tools.
Configuring Users, Administrative Settings, and Remote
Management
You can change the administrator and guest passwords and settings, configure authentication for
external users, configure an SNMP manager, backup settings and upgrade firmware, and enable
remote management.
This section includes the following subsections:
• “Changing Passwords and Settings” on page 6-8
• “Adding External Users” on page 6-9
• “Configuring an External Server for Authentication” on page 6-10
• “Enabling Remote Management Access” on page 6-14
