The only thing that I know of like this would be diald. You could set
the firewall to act as a proxy and dial on demand for the boxes behind
it. When the client wants something from the internet, it asks the
firewall for it, the firewall dials up, logs in, etc., and allows the
client machines to use it's access. I don't know if this is what your
looking for, though.
