6.7.2 How to Configure multi-WAN for Load Balancing and Failover

This example shows you how to configure multi-WAN for three WAN connections: an Ethernet WAN
connection, an ADSL WAN connection, and a 3G (cellular) WAN connection. The available bandwidth
for the Ethernet WAN connection is 3 Mbps, and the available bandwidth for the ADSL WAN
connection is 1 Mbps.
As these two wired WAN connections have different bandwidths, you can set multi-WAN to send
traffic over these WAN connections in a 3:1 ratio. Most 3G WAN connections charge the user for the
amount of data sent, so you can set multi-WAN to send traffic over the 3G WAN connection only if
all other WAN connections are unavailable.
6.7.2.1 Configuring multi-WAN
Click Network Setting > Broadband > multi-WAN. By default, all available WAN connections on
1
the Device are in active mode with a weight of 1, except for the 3G WAN connection which is set to
passive mode.
Click the Delete icon next to the VDSL WAN connection as it is not needed in this example.

DESCRIPTION
If you are adding a new entry, select the interface that you want to configure this rule for.
The list shows the interfaces that have not configured multi-WAN rules. If no interface is
shown in the list, this means all interfaces already have existing rules. You must delete an
old rule before adding a new one.
Select whether you want to configure the rule as Active or Passive. If you choose Active,
the Device always attempt to use this connection. If you choose Passive, the Device only
use this connection when all of the connections set to active are down. You can only set one
interface to passive mode.
Note: The mode of the 3G interface is locked to passive and cannot be changed to active. To
set another interface to passive mode, the 3G interface must be deleted first.
If you choose Active in the Mode field, specify the weight (1~10) for the interface. The
weights of the different member interfaces form a ratio. This ratio determines how much
traffic the Device sends through each member interface. The higher an interface's weight is
(relative to the weights of the interfaces), the more traffic the Device sends through that
interface.
