OpenVPN Scramble options can be used to obfuscate the OpenVPN connection, this can be useful to escape censoring.
It is supported by a number of OpenVPN providers e.g. TorGuard, StrongVPN, IPvanish etc. and also by DDWRT, Android and Windows.
I have made instructions how to add the necessary patches for compiling the OpenVPN scramble options into your own build and how to setup.
There undoubtedly is room for improvement, please let me know either responding in this thread or PM me,
Have fun
