Or at least to stop libvirt from inserting its rules at the *top* of the chains (which renders previously inserted rules useless)? I have VPN tunnels connecting VMs with each other and with clients, and the default rules generated by libvirt are not right for my use case. The firewall rulesets i actually need are quite simple. I am very happy to manage them outside libvirt. I am thinking of replacing /sbin/iptables with a dummy, but that is a last ressort which i hope is not necessary. Please advise /nils.
