      I just set up Suricata. Using Open Emerging Threat Rules. I have Legacy mode blocking enabled on my WAN interface. I ran nmap on my WAN IP and saw all the alerts come through, but nothing was blocked. Did I misconfigure something?

        @xoomdust You forgot to check block on drop.

        You will need to change the alert to a drop.

          @NollipfSense not that it would be ideal, but wouldn't my configuration be blocking all alerts though?

            @xoomdust said in Suricata not blocking anything:

            That's what you said!

              @NollipfSense Right, but your screenshot shows what I'm talking about. "When not checked, any rule action (ALERT or DROP) will generate a block of the offending host."

              It's not checked, yet alerts are not generating blocks of the offending host I'm seeing alerts for.
