Be careful with scrub and NFS. From http://openbsd.bay13.net/faq/pf/scrub.h=
tml

"One reason not to scrub on an interface is if one is passing NFS
through PF. Some non-OpenBSD platforms send (and expect) strange
packets -- fragmented packets with the "do not fragment" bit set,
which are (properly) rejected by scrub."
