It sounds like if_tun is compile dinto your kernel. Try "ls -l /dev/tun0". The act of looking up the pseudo-device name will cause it to be instantiated, and as such, any software that attempts to open() one will find what it needs. You only run into problems if the program tries to list the directory first to see if the file is there ("Do, or do not, there is no try.")
