pf won't start because tun0 doesn't exist yet

[Frank Steinborn]

Hi,

I'm going to set up a FreeBSD-router running pf. I have rules in
pf.conf containing rules with 'tun0'. Here is the problem:

When booting the machine, pf won't load the rules because tun0 doesn't
exist at this time. Of course I could easyilly workaround this, but I
wonder if there is a more elagant or even official way on this issue?

TIA,
Frank
