Note
In case a WAN connection goes down, all of the WAN connections with non-Always-on Connection Type will also
be brought up until any one of higher priority WAN connections is up and found to be healthy. This design could
increase the overall network availability.
For example, if WAN1, WAN2 and WAN3 have the connection types of Always-on, Backup Priority Group 1 and
Backup Priority Group 2 respectively, when WAN1 goes down, WAN2 and WAN3 will also try to connect. If WAN3
is connected first, WAN2 will still be kept connecting. If WAN2 is connected, WAN3 will disconnect or abort making
connection.
Automatic Public DNS Server Check on DNS Test Failure
In case the health check method is set to DNS Lookup and checks failed, the Balance will automatically perform
DNS lookups on some public DNS servers. If the tests are success, it means the WAN may not be down but rather
the target DNS server became malfunctioned. You will see the following warning message on the Main page.
