He meant exactly what he said:

/dev # ifconfig tun0
ifconfig: interface tun0 does not exist
[billf.yahoo-root 16:26:09]
/dev # dd if=/dev/tun0 of=/dev/null count=0

tun0: flags=8010POINTOPOINT,MULTICAST mtu 1500

/dev #
Some program needs to open() the device for it to register.
The following snippet of code (around line 155 of sys/net/if_tun.c)
is relevant:
tp = dev-si_drv1;
if (!tp) {
tuncreate(dev);
tp = dev-si_drv1;
}
.. and tuncreate() sets up the device and if_attach()s the driver,
which makes it appear in the list ifconfig works off of.

You need to open the "device-side" of the tunnel (/dev/tun0) before the interface is created.
