For pf another solution is to use '(tun0)' instead of just the plain
'tun0' when specifying the source or destination interface; that causes
the parsing to be done at runtime and allows the ruleset to be loaded
when tun0 doesn't have an IP address.
e.g use "pass out on tun0 proto tcp from (tun0) to any"
