This is "old style" PPP dial-up at 56k or lower, I take it - not PPPoA
[PPP over ADSL] or PPPoE [PPP over Ethernet] to a cable provider?
Go back to basics: stop using wvdial - perhaps remove it.
The Debian ppp package has a script called pppconfig. Run it and it
should produce a simple chat script to talk with your ISP - called
provider. It also produces simple ppp wrapper scripts (pon and poff)
Pon switches on the ppp connetion, poff switches it off.
Try that _first_ . Check that it gets you a connection.
Then configure it for demand dialling if that's what you want.

Do you have a box with two interfaces here? Is the box configured to
route from one interface to the other? Masquerading and firewall rules
may come into play here as well. Static addresses inside?
Once you have the setup working fine _then_ worry about dynamic DNS
to produce you an "almost static" IP that's advertised to and reachable
by the rest of the world.
Draw me an ASCII box diagram something like the one below if it will help.

No: too many variables here

It's tempting to rush in and try to configure everything at once. Break
the problem set down into discrete, small steps and work through them.
If you can get pon/poff to work, then work on routing traffic through
the box,then dynamic DNS.
Or have I got the scenario wrong: is this just a notebook which you want
to connect up via dial up? If that's the case and it's just that the
notebook has an ethernet jack which you wouldn't otherwise use but
set up during configuration - details please.
Read the list archives - do a Google search for e.g. PPP dial up Debian
and see what comes up.
