Description
This article shows the steps needed to configure bandwidth management (BWM). SonicOS offers an integrated traffic shaping mechanism through its Interfaces, for both Egress (Outbound) and Ingress (Inbound) traffic. Outbound BWM can be applied to traffic sourced from Trusted and Public Zones (such as LAN and DMZ) destined to Untrusted and Encrypted Zones (such as WAN and VPN). Inbound BWM can be applied to traffic sourced from Untrusted and Encrypted Zones destined to Trusted and Public Zones.
In this article there is a real configuration related to the Bandwidth Management for VoIP traffic from any source to any destination from LAN to WAN for VoIP service.
