how to make firewall changes permanent via firewall-cmd?

I am trying to open some ports in CentOS 7. I am able to open a port with the following command: firewall-cmd --direct --add-rule ipv4 filter IN_public_allow 0 -m tcp -p tcp --dport 7199 -j ACCEPT By inspecting via iptables -L -n, I get the confirmation that the setting was successful: Chain IN_public_allow (1 references) target prot opt source destination ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:7199 Unfortunately, I cannot make the changes permanent. Even by using the --permanent option like this: firewall-cmd --direct --permanent --add-rule ipv4 filter IN_public_allow 0 -m tcp -p tcp --dport 7199 -j ACCEPT Any idea on how to fix this? Why is the --permanent option not working correctly?
