      Whats the best way to block a Network Scan if the server is behind a reverse proxy and the source IP would always be the proxy?

      I would like to block this but as you can see from the alert i cant as both IPs are local to me but the scan is happening from multiple internet IPs.

        Your definition of the problem gives you the answer ... 😀.

        It can't be done using the IDS/IPS packages available on pfSense (unless you drop the proxy). The IDS cannot see the original IP address.

          @bmeeks was hoping there was some…trickery. But alas it’s reading the IP header so not much can be done
