IP Masquerade coupled with diald should do what you want. I have a Debian machine that has a modem that I use to dial my ISP. I installed/configured diald to bring the PPP/modem connection up to my ISP automatically whenever something happens on my machine that requires network access. I also have a small Ethernet LAN with one other machine (lets call is Win95). IP Masquerade allows the Win95 machine to use my Debian machine as a router (it has both a PPP connection to the Internet through my ISP and an Ethernet connection to the local LAN). Any network access that the Win95 machine requires would be forwarded to the Debian machine, which would do the "IP Masquerading" and forward the datagrams onto the Internet. If the modem connection is not up, diald will automatically bring it up and will bring it down when network access is no longer needed. I recommend the IP Masquerade Mini-HOWTO at: <http://metalab.unc.edu/LDP/HOWTO/mini/IP-Masquerade.html> I pretty much followed this verbatim and easily got it working.
