OpenSense Gateways

[grahammiranda13work2]

Hello,

Greetings from Red Cross Germany.

We have an OpnSense with 5 Gateways (see Screenshot below). The problem is if any one of the gateways go offline the other ones go offline too
For example: if our Internet-2 Gateway goes offline our VPN Connection goes offline for 10-20 seconds. It does not show offline but our Ping Breaks (Ping loss/connection lost for around 20 seconds)

Can someone please tell us where can that problem be?

The VPN is OpnSense to OpnSense  to multiple locations.  The connection restores itself too.
