I built a Web Application Firewall (WAF) using an Nginx reverse proxy to improve cheapskatesguide's robot blocking capabilities.

My goals for this firewall were mostly to provide better robot blocking and perhaps some more powerful DDoS protection than my Raspberry Pi 3 web server is capable of delivering. I still have to do some testing before I will know if my new firewall actually provides either of those, but at least I now have the additional ability to run multiple physical web servers on my LAN. Exploring that should be fun, and fun is a very important component of running a home web server.

Not my article. Just sharing.
