I am assuming that the modem connection is for dialup Internet access. If so it is absolutely doable. It has been a while since I did dialup also but I did a similar setup when sbc screwed up our dsl for about three days a year or so ago and was desperate for Internet connectivity in our office. Seems like pppd with dial on demand was what I used but it may have been simply setting PERSIST=ON now that I think about it. I would set up the linux box and get the dialup access working and then do the masq'ing of the 192.168 network. The pap or chap will depend on the requirements of your isp of course.
