Hello,
I just can open and close a port that a service running on that port?
I have not any service on port 8080 and did:
# firewall-cmd --add-port=8080/tcp
success
You're manipulating the runtime configuration.
# firewall-cmd --reload
success
Then reloading firewalld which means dropping the runtime and loading
the permanent configuration.
# firewall-cmd --list-ports
80/tcp 443/tcp
Why I can't see port 8080 in the list?
Because you reloaded. Your first command should use the --permanent
flag.
