Unix & Linux Asked by user3486308 on November 23, 2021
I have opened the 3000 port of my CentOS 7 server with the following commands:
firewall-cmd --zone=public --add-port=3000/tcp --permanent
firewall-cmd --reload
But now I want to closing them, how can I do that?
firewall-cmd --zone=public --remove-port=3000/tcp --permanent
should do the trick.
man firewall-cmd
is always at your disposal.
