It depends. natd(8) and ppp(8) use the exact same code to do NAT,
libalias(3). natd(8) has some additional options and since you can
direct what goes to natd(8) using ipfw(8) rules, there is some more
flexibility... However, that additional "flexibility" is only
something else to go wrong if you do not really need it.

Well, the most obvious thing was that you didn't have a divert(4) rule
in your firewall. But unless there is something you want to do with
natd(8)-ipfw(8) that you can't do with ppp(8) '-nat,' I'd start by
getting ppp(8) working right. If you still want to try out natd(8),
wait to do it until after you have gotten ppp(8) working correctly.
