Subject: Re: [Openstack] router cannot communicate with external


Hi,

I have installed icehouse with ovs vlan configuration.
Network node and controller node coexists.

The problem is I can ping the public IP address of my router but cannot ping external gateway from my instance.

My instance has internal IP 192.48.1.51 and a floating IP 135.252.167.187. My router has subnet 192.48.1.0/24 and gateway 135.252.167.186

[root at ih-controller neutron]# ip netns exec qrouter-e3119ff4-2fac-4226-9e63-009cfce8ac4c ping 135.252.167.1
PING 135.252.167.1 (135.252.167.1) 56(84) bytes of data.
>From 135.252.167.186 icmp_seq=2 Destination Host Unreachable
