I like the idea of Traffic Leak Protection. That said, I wanted to know where the macOS Perfect Privacy application is creating its pfctl rules from. Is there a template or a source file? I'd like to add a few custom rules as exceptions, but wasn't sure where to look. My added changes would be modular enough to not interfere with the rules the application is making. As an alternative to this, I thought I might use a firewall such as IceFloor or Murus and then effectively copy the TLP entries over, so that they're being managed elsewhere but still carry the original functionality. In that case, maybe other readers have done the same. Feel free to suggest.
