Make sure that the user is in the "dialout" group, so she can run pon
and poff to start and stop a dialin session determined by one of the
files in /etc/ppp/peers/. When ppp has brought up a link, it starts
the /etc/ppp/ip-up and passes it several parameters, among which is the
assigned local ip address.
When you install the ipmasq package, it installs a script in the
/etc/ppp/ip-up.d/ directory, that is read in turn by /etc/ppp/ip-up.
The ipmasq script will automatically setup your machine as a masquerading
gateway.
