ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv3
Manage Bandwidth Profiles for IPv4 Traffic
Bandwidth profiles determine how fast or slow data is communicated with the hosts. The
following sections provide information about managing quality of service profiles for IPv4
firewall rules:
Bandwidth Profiles Overview
Add and Enable a Bandwidth Profile
Change a Bandwidth Profile
Remove One or More Bandwidth Profiles
Bandwidth Profiles Overview
The purpose of bandwidth profiles is to provide a method for allocating and limiting traffic,
thus allocating LAN users sufficient bandwidth while preventing them from consuming all the
bandwidth on your WAN link. You can use a single bandwidth profile for both outbound and
inbound traffic.
For outbound IPv4 traffic, you can apply bandwidth profiles on the WAN interface; for
inbound IPv4 traffic, you can apply bandwidth profiles to a LAN interface. Bandwidth profiles
do not apply to the DMZ interface, nor to IPv6 traffic.
When a new connection is established by a device, the device locates the firewall rule
corresponding to the connection and the following happens:
If the rule has a bandwidth profile specification, the device creates a bandwidth class in
the kernel.
If multiple connections correspond to the same firewall rule, the connections all share the
same bandwidth class.
An exception occurs for an individual bandwidth profile if the classes are per-source IP
address classes. The source IP address is the IP address of the first packet that is
transmitted for the connection. So for outbound firewall rules, the source IP address is the
LAN-side IP address; for inbound firewall rules, the source IP address is the WAN-side IP
address. The class is removed when all the connections that are using the class expire.
After you create a bandwidth profile, you can assign the bandwidth profile to the following
firewall rules:
LAN WAN outbound rules for IPv4 (see Add an IPv4 LAN WAN Outbound Rule on
page 226).
LAN WAN inbound rules for IPv4 (see Add an IPv4 LAN WAN Inbound Rule on
page 231).
Note: For bandwidth profiles to functions correctly, make sure that you
configure the WAN upload and download settings correctly. For more
information, see Managing Advanced WAN Options on page 66.
