Create Bandwidth Profiles

Bandwidth profiles determine the way in which data is communicated with the hosts. 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. A single bandwidth profile can be 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:

•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 deleted when all the connections that are using the class expire.

After you have created a bandwidth profile, you can assign the bandwidth profile to firewall rules on the following screens:

•Add LAN WAN Outbound Services screen for IPv4 (see Figure 65 on page 141)

•Add LAN WAN Inbound Services screen for IPv4 (see Figure 67 on page 144)

To add and enable a bandwidth profile:

1. Select Security > Bandwidth Profiles. The Bandwidth Profiles screen displays. (The following figure shows some examples.)
