Hallo,
the firewall is disabled.
I tried several variations in the config-file.
0.0.0.0
192.168.242.4

Only 127.0.0.1 is working buth only withz local access.

Selinux will not allow connections on other than default http ports.

semanage port -m -t http_port_t -p tcp 9200

It's not a web server port - elasticsearch is a database.

Can you see if it is listening on 9200 on the non localhost address?

I have the line 

  network.host: 10.0.0.1

in my config that binds it to that specific IP address and I have lines
like 

java    48111 elasticsearch  382u  IPv6 1550135      0t0  TCP 10.0.0.1:vrace
(LISTEN)
java    48111 elasticsearch  530u  IPv6 1608995      0t0  TCP 10.0.0.1:wap-wsp
(LISTEN)

in the lsof output.
