    Creating a VPN Server

    Windows Server 2003 is the ideal server for setting up a Remote Access Service for your internet or intranet. Why Server 2003 and why not Server 2008? Most small businesses today are slower to adopt newer server software. Creating virtual private networks allows for the encryption and security of your assets when work with servers internally or externally. Businesses commonly overlook virtual private networks and think they are too complex to set up. These networks provide encryption when transferring files and communicating with servers.

    In the previous parts, we examined how to setup the clients to dial into one another or to a server. This guide helps you with the basics of setting up a VPN on Server 2003.

    Enabling Routing and Remote Access Service

    Click on Start, go to Administrative Tools, click on Routing and Remote Access

    After the console loads, the left pane of the console will have your local server’s name.

    A green arrow indicates the services for RRS is enabled. A red arrow indicates the service is disabled.

    Right click the server’s name and click on Configure and Enable Routing and Remote Access to start the setup wizard. Click next once the wizard appears.

    Click Remote Access (dial up or VPN will appear) to permit remote computers to dial in or connect to the server.

    Next click VPN for virtual private access.

    The VPN Connection page will show the interface. Click the network interface that is connected to the Internet and click on next.

    You should have a DHCP server on your network that assigns IP address to clients that dial in to the VPN server. Select Automatically and click next. You can specify a range of IP addresses to restrict VPN usage.

    You should elect to keep the default settings of No, use Routing and Remote Access to authenticate connection request and click next.

    Click Finish. This should enable the Routing and Remote Access service.

    Conclusion

    You should check your firewall settings if connections fail. Security suites can block outbound traffic or inbound traffic. The administrator should check any rules to ensure data is allowed out on specific ports. The most common port for a Virtual Private Network is TCP port1723. Other ports such as ports 50 and 47 may be used if GRE and ESP are used. If ISAKMP is used, it may be necessary to open UDP port 500.

    After a connection is made to the server, your workstations will obtain another internal private ip address from the server.

    It is important to train users on how to use the VPN. Scripts can be added to map network drives to the server when using your VPN. This allows the user to have or share a folder on the server and ensures that whatever data is passed between the two is secure.

    Remember VPNs play an important role in protecting your assets and critical data.
