ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv3

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

Manage WAN QoS and WAN QoS Profiles on page 74.

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 Manage Quality of Service Profiles for IPv4

Firewall Rules on page 295 and Default Quality of Service Priorities for IPv6 Firewall Rules

on page 300.

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 Manage Bandwidth Profiles for IPv4

Traffic on page 301.

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

Chapter

12, Monitor System Access and Performance.
