Before I used PPTP with Chap 2 for VPN connections to our server (Windows 2003 standard edition),
but now our manager wants to increase the security level.
I need to configure VPN through IPSec.
Please help – advise what is the best and simplest way to do it?
At the moment I don’t use any remote access policies, everything is very simple.
Can I configure VPN IPSec with using ..let’s say..preshared key?
Implementing IPSec VPN (also called L2TP) is a bit harder that PPTP. What you need to configure is different ports through the firewall, a preshared secret, or, in case of the need of higher security – a CA and digital certificates for all the users.
I would start by reading the Windows 2003 Deployment Guide:
