Some time ago I added below rule for local port forwarding

firewall-cmd --permanent --add-forward-port=port=80:proto=tcp:toport=3000

How can I remove this rule now?

You can remove it just as it was added:

# firewall-cmd --permanent --remove-forward-port=port=80:proto=tcp:toport=3000
# firewall-cmd --reload

Instead of reloading you can also change runtime settings and then make it permanent 

# firewall-cmd --permanent --remove-forward-port=port=80:proto=tcp:toport=3000
# firewall-cmd --runtime-to-permanent

    You need to remove the `--permanent` option from the first command, otherwise, this will result in no change. – guzzijason Sep 16 '18 at 06:50
