I am a new user that recently updated my account from a one month subscription to a 2-year subscription. I use OpenVPN in OpenSUSE 15.1 OS and FreeBSD 11.2 OS (OPNsense router). I use the NeuroRouting feature and find it works well and the speeds are fast enough to stream 1080p video. I like the fact you have manuals and config generators for any system. You have pfSense router manual and it works succesfully for OPNsense routers too (both pfSense and OPNsense are related, and are based on FreeBSD). For OPNsense, ther ejare a couple of tweaks needed to make it work properly: use tls-auth and not tls-crypt; leave the advanced settings box blank (adding the advanced/custom settings from the config files breaks the service). Both the pfSense and Linux .ovpn configuration files works in OPNsense routers. For desktop I just use Network Manager and import the files as-is and all works flawlessly with no needed adjustments (the Linux OS is OpenSUSE 15.1). I also use VPN of AirVPN for past many years, and think Perfect-Privacy has advantages compared to AirVPN. For those that want to use Perfect-Privacy in a multi-VPN group gateway router setup in pfSense/OPNsense (for failover fault tolerant uninterrupted service) you can visit
https://nguvu.org/pfsense/pfsense-multi-vpn-wan/. Juse remember, don't add the custom settings for the OPNsense router. If you want to learn more about OPNsense you can visit
https://opnsense.org/ . My hope for Perfect-Privacy is that more users sign up so the traffic is higher - I believe the additional noise will enhance privacy.
