Please try the attached patch and see if this works better. I've flipped the flag about explicit IPv6 support for OSX/Darwin. Your tests obviously shows the support is present. > 2. If possible, add a message about the cause to the "Cannot allocate > TUN/TAP dev dynamically" message (e.g. "permission denied" or "no tun > interface available" ,...) For now, in the patch, I've just added a bit more helpful hint. We probably could do some more checks to give a more exact error. But as this is highly platform specific, I didn't dare touching the OSX code more as I don't have access to that platform at all. kind regards, David Sommerseth

Subject: [PATCH] Fix errornous IPv6 warning for OSX and enhance TUN/TAP
allocation error
OSX/Darwin supports IPv6 in its TUN/TAP driver. Flipped the flag indicating
this support.
Further if the TUN/TAP driver in the OS is not loaded, the allocation of TUN/TAP
devices will fail. And when using dynamic allocation (when configuring tun
instead of tun0), OpenVPN will exit saying "dynamic allocation failed". Rather
be helpful and give a hint why this might have failed.
