Description

We are using a pfSense 2.0.1 on a cable line.
One IP is directly on WAN, a /28-subnet is routed to DMZ for use with VMs.

When connecting via PPTP, the error "LCP: parameter negotiation failed" occurs.

We are connecting to the single WAN IP (tried the DMZ IP too).
Tried Windows 7, XP, Mac OS X and iOS from 3 different internet lines as clients - only this VPN doesn't work, others do.
Another PPTP-VPN on the DMZ has been tested successfully - disabling this one didn't help either.

Some others have already confirmed this bug:

not a bug, that's a general problem with connectivity generally

I dont think so. In the forum others reported that the problem came or disappeared out of nowhere.
Also, other VPNs on the same connection work flawlessly.

it is. PPTP and GRE connectivity is problematic in many circumstances for many reasons. post to the forum or mailing list for further help.
