Bandwidth Limiting
Bandwidth Limiting determines the way in which the data is sent to/from your host. The purpose of bandwidth limiting is to provide a solution for limiting the outgoing/incoming traffic, thus preventing the LAN users for consuming all the bandwidth of our internet link. Bandwidth Limiting for outbound traffic will be done on the available WAN interface in the single port and Auto-Failover modes. The limiting will be done on the user-specified interface in Load Balancing mode. The bandwidth limiting for inbound traffic will be done on the LAN interface for all WAN modes. Bandwidth Limiting will not apply to DMZ interface.
Example: When a new connection is established via the device, the device will locate the firewall rule corresponding to the connection. If the rule has a bandwidth profile specifications, then the device will create a bandwidth class in the kernel. If multiple connections correspond to the same firewall rule, they will share the same class. An exception is in case of individual type bandwidth profile in which the classes are per source IP. The "source IP" is the source IP of the first packet of the connection. So for the outbound rules the source IP will be LAN side IP and for inbound rules the source IP will be the WAN-side IP. The class thus will be deleted when all the connections using the class expire.
Bandwidth Profile Table
This table lists the currently defined bandwidth profiles:
Name: Displays the user-defined name for this bandwidth profile.
Bandwidth Range: Displays the range for bandwidth profile.
Type: Displays the type for bandwidth profile.
Direction: Displays direction for bandwidth profile.
WAN: Displays the WAN for Load Balancing mode.

To remove an profile from the table, select the profile and click Delete. To edit an profile, click Edit adjacent to the profile.
Add Bandwidth Profile
Name: Specify easily identifiable name for the profile.
Minimum Bandwidth: Specify the minimum bandwidth value in Kbps for the profile.
Maximum Bandwidth: Specify the maximum bandwidth value in Kbps for the profile.
Type: Specify the type for the profile.
Direction: Specify the direction for the profile.
WAN: Specify WAN in case of Load Balancing mode for the profile.
Edit Bandwidth Profile
The following fields of an existing profile can be modified:
Minimum Bandwidth: Specify the minimum bandwidth value in Kbps for the profile.
Maximum Bandwidth: Specify the maximum bandwidth value in Kbps for the profile.
Type: Specify the type for the profile.
Direction: Specify the direction for the profile.
WAN: Specify WAN in case of Load Balancing mode for the profile.
