Upstream is thinking about removing that feature, see https://sourceforge.net/p/openvpn/mailman/message/37677365/ --- Hi, we are discussing to remove support for openvpn --mktun / --rmtun options in the upcoming 2.6 release - because it complicates the code, and we think there is no actual *need* for it anymore (and it's Linux only, etc). With "ip", there is a submode "ip tuntap", which does the same thing, so # openvpn --mktun --dev tun4 becomes # ip tuntap add mode tun name tun4 and similar for tap stuff, "user / group" settings, etc. So, this message is intended to do two things - raise awareness "this will come in 2.6!" - and also gather feedback: *if* you use openvpn --mktun today, please test "ip tuntap..." and let us know if it gets the job done properly, or of something is missing. The code is not removed yet, but will be, unless there are strong reasons to keep it. gert --- Bernhard
