I have all machines attached to the fail-over IP. So they are not connected to the main IP and can’t be reached (i hope) from that IP.
I have enabled the OVH firewall on the fail over IP too and blocked ssh (22) network traffic.
I thought i was save but now i noticed a lot of ssh log in attempts on 1 of the VM’s and when i check the originating IP-address they all seem to be OVH IP-adresses.
I have enabled the firewall of my own OS on this particular machine, but i don’t understand why this traffic could reach my server(s) in the first place.
Anyone who knows or can explain ?
