[pptp-server] Getting started on OpenBSD [Closure]

||Did you configure PoPToP using the command:
||    ./configure --with-bsdppp

Replying to myself, but especially for the archives. The problem with
running pptp on OpenBSD (version 2.7 in any event) is that by default, the
kernel will eat GRE packets. The kernel *must* be recompiled, and the
following line in the GENERIC configuration file must be commented out.

pseudo-device  gre     1       # GRE encapsulation interface

becomes

#pseudo-device  gre     1       # GRE encapsulation interface

Once this is done, pptp works flawlessly. I am not sure whether this can be
configured on the fly, but in any event compiling the kernel is simple and
fast, and you may take the opportunity to strip out a lot of functionality
that you don't need anyway.
