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
-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.
