[pptp-server] Win98 & encryption -- Unsupported protocol error

I've been looking through the FAQs and mailing
list for some time but could get no answer to
my problem - maybe someone here can help ..?

My setup is Linux 2.2.17 + mppe patch + pptp 1.1.2 and
Win98 (not SE) with either DUN40.exe or VPNUPD.EXE
(result the same problem)

the client will successfully negogiate encryption
and even sends and receives traffic for some
minutes (web browswing) but after that the pptp server log
fills up up with "Unsupported protocol received"
and the link gets unusuable.

Seems as if something in the receiving chain of
the server got broken. Any ideas ?

the problem goes away if don't use encryption.
