[root at chamber ~]# netstat -l | grep http
tcp        0      0 0.0.0.0:http            0.0.0.0:*
LISTEN
tcp6       0      0 [::]:http               [::]:*
LISTEN

Looks like it is?
Besides outside of my network this address works.

Hi,

this has nothing to do with CentOS but with your router which does not
support using the public IP from inside your network (which is quite
common).
If the port is open on your router when you access it from another
public IP then all is well. 

Regards,

  Michel
