The disappearance of the eth0 interface when you restart the net qube of the sys-firewall or set it’s net qube to none is causing `iif == "eth0"` to become `iif 2` and the rules won't work anymore. It’s better to use `iifgroup 1` instead of `iif == "eth0"`. Related discussion: https://forum.qubes-os.org/t/iptables-not-available-in-sys-net-in-qubes-os-4-2-1/26706/26
