[libvirt-users] Routed network w/o libvirt adding iptables rules

[Nils Toedtmann]

Hello

In the case of a "routed" libvirt network, is there a way to prevent
libvirt from adding *any* iptables rules? 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.
