If you have a second computer available it can be used in a fire wall router configuration even with a 16 bit version of dos on it. Routers cost less than computers though, and though I have a second dos computer, I'm not prepared to risk exposing it to the wide open internet to protect another machine without backing up its hard drive first. The thing about rp-pppoe is that not all versions of the package include the adsl-setup script especially the more recent versions, so if possible keep downloading until you come up with a complete package.
