Router namespace is not able to ping 8.8.8.8

I have configured a 3-node openstack icehouse setup. Instances are able to ping each other and to router gateway but not internet. Also Router namespace is not able to access internet. We have even applied the following rule on network node :

# sudo iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE

where eth1 is the interface for network node and bridge br-ex is connected to it. Still internet is inaccessible.

Suggest something !!

Router namespace is not able to ping 8.8.8.8

I have configured a 3-node openstack icehouse setup. Instances are able to ping each other and to router gateway but not internet. Also Router namespace is not able to access internet. We have even applied the following rule on network node :

# sudo iptables -t nat -A POSTROUTING -o eth1 eth3 -j MASQUERADE

where eth1 eth3 is the interface for network node and bridge br-ex is connected to it. Still internet is inaccessible.

Suggest something !!
