Dear Stackers,

I am running instance wordpress.WikiServer


$ nova list
+--------------------------------------+--------------------------+--------+------------------------------------+

| ddb120d9-e1ad-444c-8490-37ecb15f500e | wordpress.WikiServer     | ACTIVE
| xlcloud=172.16.1.4, 10.197.217.131 |
+--------------------------------------+--------------------------+--------+------------------------------------+


With Security Group setup as:

$ nova secgroup-list
+-----------------------------------+------------------------------------------------+
| Name                              | Description
         |
+-----------------------------------+------------------------------------------------+
| default                           | default
         |
+-----------------------------------+------------------------------------------------+


$ nova secgroup-list-rules default
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range  | Source Group |
+-------------+-----------+---------+-----------+--------------+
| icmp        | -1        | -1      | 0.0.0.0/0 |              |
| tcp         | 22        | 22      | 0.0.0.0/0 |              |
| tcp         | 80        | 80      | 0.0.0.0/0 |              |
+-------------+-----------+---------+-----------+--------------+

I can ping and ssh through the fix or floating IP without any problem
(172.16.1.4, 10.197.217.131).
But HTTP requests on port 80 doesn't go through.
I get a "no route host" error message from wget or telnet for example.

Ex. $ telnet 172.16.1.4 80
Trying 172.16.1.4...
telnet: Unable to connect to remote host: No route to host.
Clearly it's not a routing problem.

Any idea what the problem could be or hints to debug it.

Thanks
Patrick
