Does XGS 87 support dual WAN Load Balancing?

Hi Maxime75: Thank you for connecting the Sophos community team. Are you referring to WAN link load balancing with multiple active WANs on XGS87? If yes then WAN link load balancing is supported.

Yes. Many thanks

I have not tried it yet, but the GUI has options for gateway fail-over, load-balancing, and also SD-WAN routing based on application and soon (this month, when v19 comes out of early access) SD-WAN based on performance (lag, jitter, etc). I believe with load-balancing, you specify the proportion of total connections for each gateway.
