fwsnort translates Snort rules into equivalent iptables rules and generates
a Bourne shell script that implements the resulting iptables commands.
In addition, fwsnort (optionally) uses the IPTables::Parse module to parse the
iptables ruleset on the machine to determine which Snort rules are applicable
to the specific iptables policy.
fwsnort is able to translate approximately 60% of all rules from the
Snort-2.3.3 IDS into equivalent iptables rules.
