NAME
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.
