OpenVPN Client 'Killswitch' not working

[ErAzOr]

Hi,

I configured an OpenVPN client as Gateway. Only for specified Clients the traffic is routed over VPN. All other Clients through my default WAN.
So far it's working like expected.

What I now want to do is implement an 'killswitch'. So when VPN is down or not reachable, the traffic should NOT automatically routed through my default gateway.

For this I followed this tutorial:

this is my config:

My problem is, that traffic, that only should be routed through VPN, is still automatically routed through my default gateway. Even with my configuration (see screenshots).

I also tried to set Skip rules when gateway is down. But my proble still remains.

Is there anything I did wrong?
