Bandwidth Profile
The Bandwidth profile sets the limits on the bandwidth of internet link and determines the limits
on the data traffic sent to or received from your host. Bandwidth Limiting, by providing limits on
the outgoing/incoming traffic, prevents the LAN users for consuming all the bandwidth of internet
link. Bandwidth Limiting for outbound traffic is set up on WAN interface, while limits for inbound
traffic are set up on the LAN interface for all WAN modes.
Example: When a new connection is established on the VPN firewall, the firewall rules are search
for a corresponding rule limit to the connection. If the rule has a bandwidth profile setting, then the
firewall will create a bandwidth class in the kernel. If multiple connections correspond to the same
firewall rule, these will share the same class.
An exception occurs when an individual type bandwidth profile has classes set per source IP. The
"source IP" is the source IP of the first packet of the connection. For the outbound rules, the source
IP will be on the LAN side IP and for inbound rules the source IP will be on the WAN-side IP. This
class will be deleted when all the connections using the class expire.
