Dear all, I am running FlatDHCPNetwork. I have two interfaces, em1 and em2. - em1 is my flat_interface for fixed (192.168.15.0/24) and node (192.168.14.0/24) ips. - em2 is my public_interface for floating ips (192.168.16.0/24).
When I create an instance, I notice that the following iptable rule gets created: -A nova-network-snat -s 192.168.15.0/24 -o em2 -j SNAT --to-source 192.168.14.10 Strangely, the interface in the -o option seems to be always following the "public_interface = em2" configuration in '/etc/nova/nova.conf'. If I don't define it, then the rule that gets created is -A nova-network-snat -s 192.168.15.0/24 -o eth0 -j SNAT --to-source 192.168.14.10 This results in outgoing traffic from instances not being SNAT correctly, because the iptable rule is applied on the public_interface and not flat_network_bridge FWIW, I changed public_interface to vmnetbr0 (that bridges em1 and vnet0), and the instance was able to ping out. But that shouldn't be the correct configuration, should it? Can someone tell me what am I doing wrong? (I am running openstack-nova-network-2012.2-1 on fedora) /etc/nova/nova.conf ---- <snip> public_interface = em2 flat_interface = em1 fixed_range = 192.168.15.0/24 floating_range = 192.168.16.0/24 flat_network_bridge = vmnetbr0 multi_host = True Regards, WP _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
