snow,

without seeing your pf.conf ruleset, I guess you're using a ppp
connection to your upstream provider and firewalling on the tunX
interface (using tun0 as $ext_if).

As FreeBSD boots up, this interface does not yet exist when pf is
loaded. As soon as ppp is loaded and interface tun0 has been created,
pf will happily load your ruleset.

The solution is to either have pf rules loaded late (later than ppp is
started) or use anchors and load ext rules into the anchor when the
ppp interface is up. The easier is to have the rules loading late
(check using rcorder) but this may also fail if something goes wrong
with ppp.
