hi,

there is nothing really left to do. As long as you have both default routes (0.0.0.0/0) in the current Routing table (see Routing > Monitor) the FGT will use both paths. Just make sure that the distance is equal.

For load balancing method, I would switch to "source IP based" for testing; with 2 paths one will be used for hosts with odd IP addresses, and one will be used for hosts with even IP addresses. Just for testing - you can immediately check if LB is working or not.

Then, if you switch to weighted LB, specify these weights. Like "50" and "50". It is only the ratio that matters here.

after i set weighted LB to 50:50. i see from fortiview all sessions is going to Port8[Wan2] only.

For my environment, my wan1 50Mbps and wan2 32Mbps. I want to load balance and redundant internet connections, i should configure the Link health monitor?
