import-ferm (1) Linux Manual Page

import-ferm – import existing firewall rules into ferm

Synopsis

import-ferm > ferm.conf

iptables-save | import-ferm > ferm.conf

import-ferm inputfile > ferm.conf

Description

This script helps you with porting an existing IPv4 firewall configuration to ferm. It reads a file generated with iptables-save, and tries to suggest a ferm configuration file.

If no input file was specified on the command line, import-ferm runs iptables-save.

Bugs

iptables-save older than 1.3 is unable to write valid saves – this is not a bug in import-ferm.
