Yours is similar to our configuration, only with ppp 2.3.10 instead of
2.3.8.

We have some people connecting with SP6a with no problem; others get
the dreaded "unsupported protocol" error cascade repeatedly.  Tonight
we are testing my new theory that it is correlated with using a NAT
(IP masquerading) box, although I have no theory about how that could
matter.  Both problem users can do PPTP to a NT Server just fine, even
from behind their NAT boxes.

Sigh.  Weird stuff.
