[pptp-server] Running PPTP behind some firewall

[Robert Dege]

It took me forever to get PPTP to work behind a firewall.  In fact, I 
ended up finding a bug with it.  It was related with IP aliasing on the 
firewall & GRE packets getting dropped.

I'm using Linux 2.2.18 with IPChains as my firewall, and Linux 2.2.17 as 
my pptp server.
