Hi,

Often times everything work well but we get things blocked ourselves, thanks to security groups. Make sure that the secgroup you used has allowed traffic for ping and ssh.

Hi,

I followed the instructions on the [1] to configure RDO openstack with existing external network. When an instance is created , a private Ip is assigned and I manually assign a floating Ip. Everything went Ok.

However I can not access/ssh/ping instances using any of the Ips,

• Private Ip - 10.0.0.2
• Public Ip   -192.168.4.52

Routing table of the machine where RDO is installed.
