Your correction is correct.  PF turns on Self-Send, which is an AppleTalk
flag that allows packets to be directed to yourself.  In this case, it
allows NBP lookup packets to be answered by yourself.  This will be
unaffected by other people on the net.

It would be like you owning a car, and asking "Who here owns a car?".
You would answer if Self-Send (or Self-Listen) is on, but not if it is
off.  You'll notice that ALL software on the specific computer is affected.
Ex:  You can now broadcast to yourself, I can use Tops to mount a volume
that I have published (so I have the original disk, and a mounted one),
etc.

Note that SelfSend has been only recently introduced into AppleTalk, and
some Mac models may not use the appropriate drivers for this flag to
make any effect.  Inside Mac V: AppleTalk describes the Control call to
turn SelfSend on and off.  Older AppleTalk versions will ignore it.
