![]() The screenshot shows rulesets “LSI”, “LSO”, “OUTBOUND” being created. Note that user-defined iptables chains found in the configuration file will be re-created in fwbuilder as policy rule sets. The progress window displays errors, if any, as well as some diagnostics that shows network and service objects created in the process. The program tries to interpret configuration file rule-by-rule and recreates its equivalent in fwbuilder. The following example demonstrates import of iptables policy generated by Firestarter, another popular iptables configuration management program.Īfter the platform is selected and file name entered, click “Next” to start the process. Importing iptables configuration created in FireStarter The program does not make any assumptions about the file name or extension and can not predict automatically what platform is the configuration being imported is for. If you do not choose iptables in the “Platform”, the program will try to interpret the file using different parser and will fail. You also need to choose “iptables” in the drop-down menu “Platform”. Then launch fwbuilder, activate “Import Policy” function and use “Browse” button in the dialog to find file iptables_nf. To import this into fwbuilder run the script to save configuration to a file: It reads iptables rules directly form the kernel rather than from some file, so what it dumps is what is really working right now. When you run this script, it dumps current iptables configuration to stdout. Usually this script is installed in /sbin/. Script “iptables-save” is part of the standard iptables install and should be present on all Linux distribution. Iptables config that the program can import is in the format of iptables-save. Importing existing iptables configuration Only import of iptables and Cisco IOS access lists is possible in the current version. There are two ways to activate the feature: Main menu “File/Import Policy” or “Tools/Discovery Druid” and then choose option “Import configuration of aįirewall or a router”. This article demonstrates how you can import existing iptables or Cisco router configuration into Firewall Builder.
