Hi, I am running into a issue where security group rules are not applying to instances when I create a new security group with default rules it should reject all incoming traffic but it is allowing everything without blocking here is my config for nova : security_group_api = neutron firewall_driver = nova.virt.firewall.NoopFirewallDriver and in ml2.con.ini firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver iptables service is running on all the nodes, please suggest me if I miss anything. Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack-operators/attachments/20160421/c91554bd/attachment.html>
