Reboot by WAN Link loss

Hi,

I've connected both WAN ports and when I remove one wan link the RED50 restarts after some seconds. I thought the wan switch takes place without a reboot.

On the fist WAN I've configured the same IP as i used for the RED10. It's the fist WAN interface on the UTM.
The second interface on the RED50 is configured to connect to the second WAN interface on the UTM.
If I boot the RED50 with only on WAN interface connected, the tunnel is connected to the configured endpoint.
But if I boot with both WAN interfaces connected on the RED50 and remove one afterwards the tunnel is connected to the last used endpoint.

RED WAN1 -> link, tunnel active to UTM WAN1
RED WAN2 -> link

# remove link from WAN1 - RED50 restarts
RED WAN1 -> no link
RED WAN2 -> link, tunnel active to UTM WAN1
# should use UTM WAN2

Reboot with only RED WAN2 connected the tunnel is connected to UTM WAN2.


Are both tunnels opened parallel? Seems not
When yes, is there a way to see both connections in the UTM?

My UTM version is 9.003-15, and I've not used the deployment helper for the RED50.
