I cant ping/ssh instance from VM
I have setup a clean Ubuntu 14.04 and openstack icehouse using devstack script. I create 3 instances and accessed their console. But when i tried ping these instances, i got "destination host unreachable" error for one of them. Then, in this instance's console, i used "ifconfig" command and i saw it's inet address is 192.168.177.138 but in openstack dashboard interface it's ip address is 10.0.0.3. Other 2 instances' ip and inet addresses are same and i can ping them but this instance's inet address is different. I want to ask what the reason is and how can i solve this problem ?
And i want to ask a second question. One of my pingable instances had different ip and inet address before, then i softrebooted this instance and i try ifconfig command in it's console, i saw it's inet address is same with ip address. And now i can ping it. i softreboot third instance also but it's not pingable. It's ip and inet address are still different.
I'm sharing some pictures.

My pingable instance named Ankara. (it's ip and inet addresses are same) http://hizliresim.com/Q48Npg
My instance Izmir which has different addresses. http://hizliresim.com/bgZpLj
Have you any suggestions ? Thanks for your help.
It seems that your instances possess all a correct IP on tour private (tenant) network and on the external (public) network. Can you please neutron net-list. neutron subnet-list, nova list, neutron subnet-show "your subnet(s) id" Also, there are a lot "I can't ping " topics. Have a look first :)
Also can you please edit your post with some configuration log like this man did. Thank you very much
have you added rules in default security group with all icmp ans ssh.
Hi SGPJ, yes i've added all icmp, all tcp and ssh rules. my problem is i can ping some instance but i cant ping others. one instance (named Izmir) is not pingable. i'm not sure but it's ip and inet address are different and i thought i cant ping it because of this difference.
