4.5 Other WAN Traffic Settings
It is a good idea to have two Internet feeds to the system, especial from two different ISP; it adds the service
reliability to your clients by turning on WAN-Failover feature. When one feed is out-of-service, the other feed
automatically picks up the responsibly of serving the clients under the feed that goes outage.
By default, the system assumes there is only one feed to WAN1. All the Policies by default route all clients' internet
traffic via WAN1, using the Internet pipe at WAN1. When you have two pipes, you certainly want to set some Policies
to utilize the bandwidth of the second pipe at WAN2, rather then just when the WAN1 pipe fails.
Beside the static load balancing by setting "Policy" route, alternatively, you can use the system's dynamic
Load-Balancing feature. When the feature is turned on, the system can distribute the load of the up-going traffics to
the two WAN pipes, according to the weight percentage assigned by the administrator.
5.2.2 WAN Failover
Configure WAN Failover:
Go to: System >> WAN Traffic.
Enable WAN Failover: Normally WHG-505 uses WAN1 as it primary WAN interface. When WAN Failover is
enabled and WAN2 is available, WAN1's traffic will be routed to WAN2 when WAN1 connection is down. On the
other hand, a Service Zone's policy could also use WAN2 as its interface; in that case, if WAN2 is down, the
WAN2's traffic under its policy will also be routed to WAN1.
Fall back to WAN1 when WAN1 is available again: If WAN Failover is enabled, the traffic will be routed to
WAN2 automatically when WAN1 connection fails. When fall back to WAN1 is enabled, the routed traffic will
be connected back to WAN1 when WAN1 connection is recovered.
5.2.2 Load Balance
Configure Load Balance
Go to: System >> WAN Traffic.
