Check out the newest addition to my home network! It’s a raspberry pi-zero w/ Debian, configured with a firewall program that filters a ton of unwanted traffic out of my network. It also acts as my local DNS server!
Here is the web-based front end of the device and an example of how much traffic it blocks for me. It’s been a useful tool for helping me learn to parse through logs to see where problems might occur when something is incorrectly blocked.
