import−ferm − import existing firewall rules into ferm
import−ferm > ferm.conf
iptables−save | import−ferm > ferm.conf
import−ferm inputfile > ferm.conf
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.
iptables−save older than 1.3 is unable to write valid saves − this is not a bug in import−ferm.
