same as dars. more than likely the problem. i sent dars a test ovpn that i knows works if he gets the same issue then we know its the image.
im assuming your getting the same error as below?
Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2)
I was!! but I'm now getting no such file/directory......ive been mucking about with that many files I dunno whats what now!.....ill start again if I need to install a new image.
