Spent hours trying to set this up, and I finally got it working. Had to tweak a bunch of configs, figure out the right certs, and fight with some port forwarding. Thought I had it, then I realized my firewall was blocking some traffic. Gah. Still not sure if my speeds are legit or just random noise. Anyone got a reliable guide or quick tips for troubleshooting OpenVPN on Pi? Feeling pretty proud but also pretty stuck.
