This software converts snort rules into iptables rules, making it easier to implement network security measures.
In addition, fwsnort utilizes the iptables string match module, along with a custom patch that adds a --hex-string option to the iptables user space code. This allows for the detection of application level signatures, which is a handy tool for those trying to detect and prevent attacks.
Another useful feature is fwsnort's optional use of the IPTables::Parse module, which can translate snort rules for which matching traffic could potentially be passed through the existing iptables ruleset. Overall, I found fwsnort to be a very effective and flexible tool for building iptables rules from Snort rules. It's definitely worth giving a try!
