Wireless-G VPN Boradband Router

Appendix C: Configuring IPSec between a Windows 2000 PC and the Router

Introduction

This document demonstrates how to establish a secure IPSec tunnel using preshared keys to join a private network inside the VPN Router and a Windows 2000 or XP PC. You can find detailed information on configuring the Windows 2000 server at the Microsoft website:

NOTE: Keep a record of any changes you make. Those changes will be identical in the Windows “secpol” application and the Router’s Web-Based Utility.
