[pptp-server] NAT Installation

[Ali Lahooti]

Hi,

I am in a process of installing NAT (NETWORK ADDRESS 
TRANSLATION) software to configure a VPN firewall.

I have received these instructions from the following URLs:

http://www.moretonbay.com/vpn/releases/HOWTO-PoPToP.txt

and have downloaded NAT from the site below.

http://www.csn.tu-chemnitz.de/HyperNews/get/linux-ip-nat.html
However, I have problems installing NAT.  Here is more information, 
please advise where can I find the missing file(s) or what I am doing 
wrong.  Thanks in advance.
