DIALD is exactly what you are looking for - it stands for DIAL on
Demand. We have a similar scenario to yours, but we built a custom service
where users have to authenticate because we wanted to have a queue to
avoind disconnecting a few seconds after someone hung up.
DIALD by itself will not solve your problem, you need to set up
the Linux box to do masquerading, but it's pretty simple (there is a
HOWTO), and you have to set up some simple ipfwadm or ipchains (for kernel
2.2) rule sets. If you have other Linux boxes on the network, you need to
enable masq on them too.
One difficulty we had with DIALD is that the dial-up connection is
almost never up and running fast enough, so the browser usually gives up
claiming "time-out" errors. But, then again, this may be a problem with
our phone lines, our ISP, or because we are not using the latest versions
of DIALD (it jumped from 0.16 to 0.9x a few months ago) yet.
I saw once a DIALD tool that allowed you to control the DIALD
server from a Win client, but I don't remember the name now...
Good luck!
