5.6.2 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/4G (mobile) 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 3:2 ratio. Most 3G/4G WAN connections charge the user for the
amount of data sent, so you can set multi-WAN to send traffic over the 3G/4G WAN connection only if
all other WAN connections are unavailable.

DESCRIPTION
To move an interface to a different number in the list, click the Move icon. In the field that
appears, specify the number to which you want to move the interface.
This column displays the priorities of the group's interfaces. The order of the interfaces in the list is
important since they are used in the order they are listed.
Click this table cell and select an interface to be a group member.
Click this table cell and select Active to have the SBG always attempt to use this connection.
Select Passive to have the SBG only use this connection when all of the connections set to
active are down. You can only set one of a group's interfaces to passive mode.
This field displays with the weighted round robin load balancing algorithm. 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 SBG assigns to each member interface.The higher an
interface's weight is (relative to the weights of the interfaces), the more sessions that interface
should handle.
This field displays with the least load first load balancing algorithm. It displays the maximum
number of kilobits of data the SBG is to allow to come in through the interface per second.
Note: You can configure the bandwidth of an interface in the corresponding
interface edit screen.
This field displays with the least load first or spillover load balancing algorithm. It displays the
maximum number of kilobits of data the SBG is to send out through the interface per second.
Note: You can configure the bandwidth of an interface in the corresponding
interface edit screen.
This field displays with the spillover load balancing algorithm. It displays the maximum number of
kilobits of data the SBG is to send out and allow to come in through the interface per second.
Note: You can configure the bandwidth of an interface in the corresponding
interface edit screen.
This field displays with the spillover load balancing algorithm. Specify the maximum bandwidth
of traffic in kilobits per second (1~1048576) to send out through the interface before using
another interface. When this spillover bandwidth limit is exceeded, the SBG sends new session
traffic through the next interface. The traffic of existing sessions still goes through the interface on
which they started.
The SBG uses the group member interfaces in the order that they are listed.
