The closest thing I could find to an iptables to firewalld conversion tool was Offline Configuation. The firewall-offline-cmd command was created to help setup firewall rules when Firewalld is not running. For instance, to open the tcp port 22, you would type in the /etc/sysconfig/iptables file: -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT Instead, you can now execute the following command: # firewall-offline-cmd --direct --add-rule ipv4 filter INPUT 0 -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT / / / / / / / / / / / / / / / / / / / / / / / / / // / It's not that convenient for a rule-set of 250 lines, but with a little creative copying/pasting between the iptables rules and the "firewall-offline-cmd --direct -add-rule ipv4 filter" and "firewall-offline-cmd --direct -add-rule ipv4 nat " statements, I suppose a decent conversion can be completed. Of course, you'd still need to apply rules to the correct zones which I'm still trying to digest.
