Hi all, I have an Test tenant create and i have one Test CentOS up and running. The machine works perfect. I have add ssh port and works perfect. After a some time i note that i cant ping http://www.google.com but i can ping 8.8.8.8. I add port 80 from security group rules ( and yes resolve.conf is ok ) but still same problem. And i try scanning the machine with nmap and i see that port 80 is closed.

Any hints about it ?

 nova secgroup-list-rules default
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range  | Source Group |

| tcp         | 22        | 22      | 0.0.0.0/0 |              |
|             |           |         |           | default      |
| icmp        | -1        | -1      | 0.0.0.0/0 |              |
|             |           |         |           | default      |

And this is the output of the nmap scanning that instance public ips

PORT   STATE  SERVICE
22/tcp open   ssh
80/tcp closed http

And this is the output of the iptables of the instance
