[pptp-server] Data Compression

I did a bit of playing with this, I don't believe that pppd can support
microsofts mppc compressionm scheme.  From the pppd readme:
 
Compression methods.
********************

This package supports two packet compression methods: Deflate and
BSD-Compress.  Other compression methods which are in common use
include Predictor, LZS, and MPPC.  These methods are not supported for
two reasons - they are patent-encumbered, and they cause some packets
to expand slightly, which pppd doesn't currently allow for.
BSD-Compress is also patent-encumbered (its inclusion in this package
can be considered a historical anomaly :-) but it doesn't ever expand
packets.  Neither does Deflate, which uses the same algorithm as gzip.

 

Thanks,
