      Assuming you've got pfSense next to your Internet connection, nothing. PfSense is your protection for your network.

      PfSense running on Qotom mini PC
      i5 CPU, 4 GB memory, 32 GB SSD & 4 Intel Gb Ethernet ports.
      UniFi AC-Lite access point

      I haven't lost my mind. It's around here...somewhere...

            it consumed my all the bandwidth on my routers

            You can not protect against a volumetric attack at your device.. The attack has to be addressed upstream of your pipe..

            If the pipe is full the pipe is full, there is nothing you can do at your end of the pipe..

                Talk to your ISP, needs to be fixed further up the chain.

                  You need to get with your ISP on a volumetric attack, unless your advertising your own network space and could use a method of RTBH (Remotely-triggered Blackholing)...

                      Keep in mind that ddos protection from your ISP normally comes with some sort of cost..
