I’ve been writing about Suricata on pfSense for a minute. In the last post I dug into why the stream rules don’t work for Suricata on pfSense.

In this post, I want to look at the individual network packets that triggered the alerts.

Enable packet capture

Before you can look at any packets triggering Suricata alerts, you have to enable packet capture.

Navigate to Suricata as I showed you in prior posts.

Services > Suricata

Click on the pencil icon next to an interface.

On the Settings tab …

Scroll down and check the box next to Enable Packet Log.
