Description
I've opened the 9092 TCP port in my VM (130.206.126.234) and it is not accessible from the outside.
I've run a netcat listening in that port:
$ nc -l 9092
Then I've run a telnet from a remote machine (e.g. my laptop):
$ telnet 130.206.126.234 9092
Trying 130.206.126.234...
telnet: connect to address 130.206.126.234: Operation timed out
telnet: Unable to connect to remote host
Please, have a look on the attachment in order to check the port is opened.

Francisco

If you need to disable the internal firewall in your CentOS, you can do this by running this two commands as root:
