PPTP VPN question

[d.antunes at comcast.net]

Hello All,
I am running 4.9-RELEASE-p2 with poptop-1.1.4.b4_3 and am having trouble forcing MPPE of any strength. Windows clients will only connect successfully if encryption is not required of the connection. I have tried multiple entries in ppp.conf (conflicting, I might add) found both while googling and in thesystem-provided sample ppp.conf file. Can anyone out there share with me a working ppp.conf? Is there anything else required to support MPPE?
Thanks for your help.
Dennis
