Not true.
As far as I can tell, these warnings are harmless - the filters will be
added as normal and will take effect once the tun0 device actually is
created.
You can also create the tun0 device by doing something like:
echo < /dev/tun0
prior to the ipfw add - the tun# devices are created at first open.
Probably something like this should be added to rc.firewall.
