Can I Configure a WAN Connection as Backup Only?

Yes, failover is fully supported in Peplink Balance besides link aggregation and load balancing. The kinds of WAN connection (DSL, Cable, 3G…etc.) supported are not limited, thus you can simply set a 3G or other kinds of connections as a backup. The only thing you need to do is configuring the WAN connection type and health check on the Web Admin Interface of Balance. Once your preferred connection is disconnected, the backup connection will come up. When the preferred connection come back to live, the Balance will simply shift back to use your preferred connection.

Configuring Connection Type

In order to configure WAN connection type to Always-on or Backup Priority, please follow the set up procedures below:

  1. Go to Network > Interfaces > WAN > (preferred connection) and select Always-on as Connection Type. This WAN will then be your preferred connection.

Configuring Health Check Settings

Configuring the Connection Type allows all traffic to pass through a pre-defined WAN. Regular health check ensure up-to-date link statuses. In case of your preferred link failure, Peplink Balance automatically re-routes traffic to a healthy link to provide continuous Internet service.

  • In the Health Check Settings of the same page, select DNS Lookup as Health Check method (for every connection which you would like to use for failover). For more information, please refer to this FAQ.
