[pptp-server] pptp crypting

[Justin Kreger]

IPSEC and PPTP are two diffrent protocols.  PPTP has NO encryption once so
ever.  IPSec has two sub protocols, AH and ESP.  AH provides no
encryption, but it is used to make sure that the data from the source is
authentic, ESP can encrypt host to host communications, and also encrypt
ip-ip tunnels, allowing you to connect large private networks over the
internet with ease.

You can use IPSec on two hosts, and then create a pptp tunnel between
them, but its easyer with most implmentations of ipsec to just have ipsec
do the ip-ip tunnel.
