12.5 Bandwidth Management - Lite

Bandwidth management lite allows you to use firewall rules to perform basic bandwidth management.
You can apply bandwidth management to firewall rules based on applications, IP addresses (including
individual IP addresses, ranges or subnets) or a combination of the two.
You can use bandwidth management to guarantee bandwidth for delay-sensitive applications such as Voice-
over-IP (VoIP). You can also limit the bandwidth used by bandwidth-hungry applications (or individuals) by
allocating the maximum bandwidth for traffic that matches a firewall rule.
Enable bandwidth management in the BM Global Setting screen and apply bandwidth management to
individual firewall rules in the Firewall Edit Rule screen (go to the Summary screen and click Insert to
create a new rule or select an existing rule's radio button and click Edit to edit the rule).
