I disagree with this "solution". Whilst a 5 or 10 second sleep may work
for you today, it may not work tomorrow (when your ISP's servers are
a bit busier). It is unlikely to be appropriate for everyone.
It shouldn't be too difficult to force the rc.d scripts to synchronise
to the PPP link:
1) Create a "ppp.linkup" that creates a flag file somewhere
2) Create a rc.d script with "after ppp, before pf" (or whatever)
that waits for the flag file to appear (and then deletes it):
until [ -f /flag/file ] ; do sleep 1 ; done
(add error checking to suit)
