Hi,

I have installed single node openstack from devstack and booted two cirros machine instances. I am using OVS plugin for my work.

The instances are able to ping the outside world including public IP address as 69.171.224.42 (facebook) and 74.125.224.72 (google). However, when i ping from the host machine to the instances i get an error message ping: sendmsg: operation not permitted

The configuration is as follows:

Configuration of the router: Interface towards external bridge, br-ext, : 172.24.4.226

Interface towards integration bridge, br-int, : 192.168.0.1

I am able to ping the ip address 192.168.0.1 and 172.24.4.226 from the host machine.

Configuration of the Instances:

Instance #1 IP address: 192.168.0.3

Instance #2 IP address: 192.168.0.1

Default Security Group Rules:

Rule ALL TCMP and ALL ICMP Direction Ingress.

The machines are assigned fixed IP address from network 192.168.0.0 and I am able to ping 192.168.0.1 from the host machine.

According to route-n command The Gateway for an address in the network 192.168.0.0. is 172.24.4.226.

If anyone could help on this, i would really appreciate it. Thank you.
