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 traffic, you can apply bandwidth profiles on the WAN interface; for inbound
traffic, you can apply bandwidth profiles to a LAN interface. Bandwidth profiles do not apply to
the DMZ interface.
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 co
nnections 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 W
AN Outbound Services screen (see Figure 55 on page 118).
• Add LAN W
AN Inbound Services screen (see Figure 56 on page 119).
 To add and enable a bandwidth profile:
1. Select Se
curity > Bandwidth Profiles. The Bandwidth Profiles screen displays. (The
following figure shows some examples.)
