I am stunned!
I did that task by using firewalld and then it failed. I asked for review and a person said you need to do this using iptables.
Deprecated things ? seriously? and the machine was also centos 8 LOL. Iptables?
I need @rana to look into this and clear this task.
It’s still around! I have to work with it from time to time in my day job. Lot of corporations still running RHEL 7 - because it’s battle tested and not EOL yet!
I don’t know the task, but did it explicitly mention to use iptables?
