ppp is for calling in with a modum on a telefone network. It doesn't
work as a stand alone for a ADSL modum. There a couple of ports avalible
for ADSL modums. (pptpclient is one) But is feel its better to have
something more independed. Can you modum be setup so it connects on its
own?

I have a PPTP connection over my ADSL modum. I've configured my modum so
that it builds the connection and routes the packets though on regular
ip connection to my computer. It does take configuring of you FreeBSD
box this way.

Its proberbly best to go for something in bewain first like setting your
modum up to be a nat router.
