natd doesn't work in 2.1.*. The divert stuff wasn't stable enough.
Certainly, if there was divert stuff there back then, the -p option
doesn't work - you need the -i & -o options instead (there was a problem
with the divert loopback avoidance code).

I'd suggest going to at least 2.2.1 if you want natd, otherwise
use ppp -alias if you're masquerading on a serial interface.
