It would be great if there were a way to specify speedfusion asymmetric WAN priority like this:
WAN1 - priority: 1, direction: up/down
WAN2 - priority: 2, direction: up
WAN3 - priority: 2, direction: up/down
WAN2 - priority: 3, direction: up/down
This would mean that if WAN1 is down, and both WAN2 and WAN3 are available, then WAN2 will function asymmetrically potentially increasing the outbound speedfusion capacity by sending some outbound speedfusion traffic via both/either WAN2 and WAN3. But then if WAN3 goes down such that only WAN2 is available, the speedfusion link will keep working (albeit slower and using only WAN2’s capacity).
