[Bug 595501] [NEW] iptables rules for NAT break ufw setups

[Loïc Minier]

Public bug reported:

Hi there

If one tries to use libvirt vms with a NATed network, libvirtd will
insert iptables rules before the earliest ufw rules (ufw-before-forward)
in the FORWARD chain, and so breaks ufw semantics.

It would be nice if libvirt could have a special handling for the rules
if ufw is present.

Thanks!
