Hi there,
Unsure of whether or not to file this as a bug or not but here goes:
With MultiWAN enabled and 2 WANs set with metric 200 and 300 (failover in WAN1/SFP+ is my primary fiber WAN for multigig) whenever fiber goes out it switches over but does not switch back until I physically unplug the port as there is no way I know of to cycle the port via the busybox interface as it seems that the debian ssh shell is not user acessible via the shift click menu on manage.alta.inc
An interesting sidenote is that iperf3 will only run via WAN1 unless the failover is unplugged physically it will always default to using the faikover (WAN1) when using --bind to switch the interface it does not switch it keeps throwing an error.
