The tun? interfaces are created when a device tries to read from them.
For example, I currently have tun0, because of my PPP link.
# ifconfig -a | grep tun
tun0: flags=8150<POINTTOPOINT,RUNNING,PROMISC,MULTICAST> mtu 1500
If I now try and read from /dev/tun1, using cat(1), the interface tun1
will be created.
# cat < /dev/tun1
^C
# ifconfig -a | grep tun
tun0: flags=8150<POINTOPOINT,RUNNING,PROMISC,MULTICAST> mtu 1500
tun1: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
For you, tun0 will be created when you run a program that tries to use it.
