[Openstack] iptables performance issue

Hi all, Currently, openstack heavily uses iptables in network setup(firewall, NAT, etc.), which may trigger performance issue on some situations. For example, I have ever found packet dropping in host for several times, due to connection tracking triggered by NAT. By now, I have to find some stu
