[pptp-server] RE: Protocol-Reject Issue

[Leonard L. Goldenstein]

One thing I did forget to mention is that the VPN connection works great
without encryption when I don't have the mppe-40,  mppe-128, mppe-stateless
options in the pppd config.

As soon as I get encryption running, nothing works except the login.

Help? :)
