That doesn't look right. What happens if you leave that out? Perhaps it's
not appropriate for you.

It does seem like some kind of routing problem. The usual way to run nat
is to have your hostname translate to the internal address, and then to
have your default route be the external address. When the external link is
a ppp connection, "defaultroute" in the options file is sufficient to do
that, but in your case, you will probably have to force it with something
like `route change 216.164.32.41 default'. I recommend to first examine
the output of `route show', and then experiment until you get it right. Do
you have an /etc/ifconfig.sn0 file? Perhaps the word "default" should go
in there.

Also, be sure to check out the documentation at the IP Filter Home Page
