Hi Chris,<br>
how do you start suricata? did you find any errors about ipfw in the logs?<br>
If you set up a ipfw divert socket, then you need an app connected to<br>
it in order to forward packets. Usually, packets are not forwarded if<br>
there's no listening application delegated to allow/deny packets.<br>
