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
1 Click Network Setting > Broadband > multi-WAN. By default, all available WAN connections on
the SBG3500-N Series are in active mode with a weight of 1, except for the 3G WAN connection
which is set to passive mode.
2 Click the Delete icon next to the VDSL WAN connection as it is not needed in this example.
3 Click the Edit icon next to the ETHWAN-SFP WAN connection. This brings up the edit window.
Change the weight field to 3 and click the Apply button.
4 You have finished the configuration. When both the ETHWAN-SFP and ADSL connections are up, the
SBG3500-N Series will send traffic over these two connections in a 3:1 ratio. When only one of
these two connections are up, the SBG3500-N Series will use that connection exclusively. Only
when both of these two connections are down will the SBG3500-N Series use the 3G connection.
