Question:

I have setup WAN1 as Active mode and WAN2 as Passive mode in trunk setting. But why the traffic still keep on WAN2 interface even the WAN1 interface has faillback completely?

Answer:

If you would like to disconnect all of the exist sessions from WAN2 when WAN1 interface has fallback completely, then you can enable "Disconnect Connections Before Falling Back" function. It will disconnect all of exist sessions from WAN2 interface, and it means all of incomplete sessions needs re-initial from client again.
