Introduction
The ISA Server 2004 firewall can be configured as a VPN server. The VPN server component enables it to accept incoming VPN client calls so that the VPN client computer can become a member of a protected network. Traditional VPN servers allow VPN clients full access to the networks to which they connect. In contrast, the ISA Server 2004 VPN server allows you to control what protocols and servers VPN clients can connect to, based on the credentials used when connecting to the VPN server.
You can use the Microsoft Internet Security and Acceleration Server 2004 management console to manage virtually all aspects of the VPN server configuration. The firewall manages the list of IP addresses assigned to VPN clients and places those addresses on a dedicated VPN clients network. Access controls can then be placed on communications moving to and from the VPN clients network using Access Rules.
In the following walkthrough, perform the following tasks to enable the ISA Server 2004 VPN server to:
•Enable the VPN Server
•Create an Access Rule allowing VPN clients access to the Internal network
•Test the VPN Connection
