Creating an OpenVPN Configuration for ChromeOS

This assumes you already have an OpenVPN server set up that you'll be connecting to. OpenVPN server setup is not covered in this document.

NOTE: ChromeOS is VERY picky about adherance to the ONC filespec (second ref. link). If an option is marked as an integer, and you surround it in quotes, import of the file will fail silently. Booleans (true and false) seem to be an exception wherein you can either wrap, or not, the boolean value in quotes without it failing ¯\_(ツ)_/¯.

• https://chromium.googlesource.com/chromium/src/+/master/components/onc/docs/onc_spec.md#OpenVPN-type

ChromeOS supports both L2TP and OpenVPN VPN connections. However, adding an OpenVPN connection, other than a really basic one, is non-trivial, as many options are missing from the GUI; things such as setting the Cipher or the Auth types, setting CompLZO, or any myriad nonstandard
