Michaël Perrin asked:
I would like to open port
4567 for the IP address
18.104.22.168 with the
firewall-cmd command on a CentOS 7.1 server.
How can I achieve this, as the documentation I could find was too specific on this?
Create a new zone to accommodate this configuration. FirewallD zones are defined by source addresses and by interfaces.
firewall-cmd --new-zone=special --permanent firewall-cmd --zone=special --add-source=192.0.2.4/32 firewall-cmd --zone=special --add-port=4567/tcp
--permanent of course to the latter two commands to make them permanent.
