2014-06-17 15:44:54 -0500 asked a question Instances unable to reach DHCP, ping other instances,router.

I have been stuck for about a week and have gone through every troubleshooter i could find. The instances could not reach the dhcp so they self assigned an ipv6 address. I assigned a static ipv4 that they were supposed to have and they can ping another instance as long as they are on the same node. They are unable to ping the router or anything outside of it. Using ip netns exec to get into the routers namespace I am unable to ping the machines on the network or outside the network as well. I was unable to find anything in the error logs except the neutron one mentioned below.
