How 2 use slirp with pptpd-0.9.0

o Grab the slirp-1.0c package and install it
  ftp://blitzen.canberra.edu.au/pub/slirp/slirp-1.0c.tar.gz
  (other versions might work also, but were not tested)

Then install pptpd

o ./configure --with-slirp

o Set path to slirp in config.h right

o Be sure to have a HOME variable set when you start 
  pptpd, because slirp reads the HOME/.chap-secrets file
  for authentication
  This file must be filled in the same way as the 
  chap-secrets for pppd

o For the rest follow the pptpd instructions

o I have tested this with a Solaris 2.4 server, gcc and 
  pptpd running on this configuration. As client I used 
  Win95 DUN 1.3. I only tested this on a local network because 
  our routers still block port 47.
  With this test I get a clean authentication.
