Webmin+erro firewall

Galera o webmin esta falando ke tenho 2 iptables ... por ke sera isso ?
olha a mensagen ke ele deixa:

Webmin has detected 2 IPtables firewall rules currently in use, which are not recorded in the save file /etc/sysconfig/iptables. These rules were probably setup from a script, which this module does not know how to read and edit.

If you want to use this module to manage your IPtables firewall, click the button below to convert the existing rules to a save file, and then disable your existing firewall script.
