Translates snort rules into an equivalent iptables ruleset

'fwsnort' translates snort rules into an equivalent iptables ruleset. By using the iptables string match module, fwsnort detects application layer signatures which exist in many snort rules. It adds a --hex-string option to iptables, which lets users directly input snort rules that contain hex characters into iptables rulesets without modification. 'fwsnort' also uses the IPTables::Parse Perl module to (optionally) restrict the snort rule translation to only those rules that specify traffic that could potentially be allowed through an existing iptables policy.
