Use QoS and Bandwidth Assignment to Shift the Traffic Mix

By setting the Quality of Service (QoS) priority and assigning bandwidth profiles to firewall
rules, you can shift the traffic mix to aim for optimum performance of the VPN firewall.
The following sections provide information about using QoS and bandwidth assignment to
shift the traffic mix:
• Setting QoS Priorities
• Assigning Bandwidth Profiles
Setting QoS Priorities
The QoS priority settings determine the Quality of Service for the traffic passing through the
VPN firewall.
You can create and assign QoS profiles to WAN interfaces. For more information about QoS
profiles for WAN interfaces, see
You can also create and assign a QoS profile (IPv4) or QoS priority (IPv6) to LAN WAN and
DMZ WAN outbound firewall rules. QoS is set individually for each firewall rule. You can
change the mix of traffic through the WAN ports by granting some services a higher priority
than others in the following ways:
• You can accept the default priority defined by the service itself by not changing its QoS
priority.
• 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.
For more information about QoS profiles, see
Firewall Rules on page 293 and
on page 298.
Assigning Bandwidth Profiles
When you set the QoS priority, the WAN bandwidth does not change. You change the WAN
bandwidth that is assigned to a service or application by applying a bandwidth profile to a
LAN WAN inbound or outbound rule. The purpose of bandwidth profiles is to provide a
method for allocating and limiting traffic, thus allocating sufficient bandwidth to LAN users
while preventing them from consuming all the bandwidth on your WAN links.
For more information about bandwidth profiles, see
Traffic on page 299.

Monitoring Tools for Traffic Management

The VPN firewall includes several tools that can be used to monitor the traffic conditions of
the firewall and content-filtering engine and to monitor the users' access to the Internet and
the types of traffic that they are allowed to have. For a description of these tools, see
