All Barracuda Link Balancer models, firmware version 1.2 and above
If you do not want all WAN interfaces to balance outbound connections, you can change this behavior using the Link Preferences table on the Services > Bandwidith Mgmt page. The supported link types are:
- Primary links ? used first for outbound link balancing.
- Backup links ? used only if the primary links are down or if they become saturated (80% of capacity).
- Private links ? used exclusively for traffic that matches Quality of Service rules that specify those links or for Virtual Private Networks.
Private links are used exclusively for Quality of Service rules (QoS) or Virtual Private Networks (VPN).
QoS rules and VPNs may use any WAN links: they are not limited to Private links.
