You should keep default_router="NO"

You want natd to alias packets over ppp0. If you thing about it, it
should make sense.
Therefore just change 'via ed0' to 'via ppp0'. Also unless you have a
static ip address
it might be best to include a -dynamic switch to natd to save having to
restart it every
time you dial. So you'll want to use 'natd -dynamic -n ppp0'. That
should get you started.

Good luck,
