Hello Vince,
Thank you for your response, but unfortunately adding
cloned_interfaces="tap0" to my rc.conf did not solve the issue. The
tap0 device only appeared after I started the openvpn daemon. Is there
a way to determine the order to start the daemons. Maybe I can solve
the problem in that way.
I wonder why it is so hard to accomplish this. FreeBSD is usually very
intuitive in initialising device support. Naively I would think: load
the kernel_module and run ifconfig and you are there. For xl0 and rl0
it will work like this, I guess, but for tap0 certainly not. What kind
of a kick does this tap device need? Is it that special? Openvpn needs
to know which tap to use, but that is it, I guess. The rest is up to
the kernel to do the trick, isn't it? Maybe I have to dig in the source
code of openvpn to find out how to initialise the tap device.
