How to do load balancing with multiple external lines with the operator?

For the need of bandwidth, the local area network often adopts the way of multi-external access, which can stack the bandwidth and prompt the bandwidth, and can also back up each other. Once one line is interrupted, the other line can continue to be used to ensure the normal operation of the network.

This article will introduce how to use WFilter NGF (WSG) to achieve multi-line load balancing and line detection with ISP.

1. Configure load balancing

The same operator does not have the problem of line DNS, so you can directly carry out load balancing. In the "multi-line balancing" module, you can create a load balancing line solution. As shown in the figure:

Then select the appropriate line scheme for the client of the intranet:

two。 Open line detection

Line detection can detect the unblocked condition of each WAN port. Once it detects that the line is blocked, the WAN port will be removed from the load balance to ensure the smooth operation of the network. The configuration is as follows:
