Qubes OS 4.2 nftables / nft firewall guide

Agreed. Thanks for opening this topic, @Solene.

Btw, do you know why R4.2 used to work but the new update that made VPNs dysfunctional was viewed as an improvement? Were there leaks or security flaws? Online auditors and cli status showed my VPN configuration to be working with the values it was designed to. Is there something hidden in this iptables complexity you could elucidate?

And does anyone know what these “start” IPs refer to in the output highlighted here? What are -t -nat --flush PR-QBS all about? No simple path for Rise Up now, is there?
