I tried testing the killswitch, so I stopped networkmanager inside the sys-vpn, but I still had somehow connection to the sys-vpn and my ip didn’t change. How does that even work? And how can I test the killswitch? Could you also make a NFT rule to block ICMP/ping to add into the qubes-firewall-user-script? Also what is the difference between this guide and this one [Tutorial 4.2&4.1] Mullvad Wireguard with Qubes - #53 by qubes-neurotic ?
