A firewall that utilizes the Linux kernel's XDP hook. The XDP hook allows for very fast network processing on Linux systems. This is great for dropping malicious traffic from a (D)DoS attack. IPv6 is supported with this firewall! I hope this helps network engineers/programmers interested in utilizing XDP!
