I did this a looooong time ago, so visualize me waving my hands
frantically.  You presumably want the "-n" flag (detaches from stdin),
or possibly the "-f" flag (implies "-n" but allows prompting for a
passphrase, but that doesn't seem to be appropriate for a service).

The man page is pretty good, and has a discussion of using the tun(4)
network pseudo-device.
