<p>VPN  (Virtual  Private  Network)  refers  to  two  different  equipment  (a  computer  and firewall) with VPN link capability which can form a secure tunnel over the internet. In the tunnel initiator (server), A user’s private data is encapsulated and encrypted, and then  transmitted  on  the  internet;  in  the  receiver  side  (client),  the  received  data  is unpacked and decrypted. VPN services are installed with Windows 2000/2003. This manual is based on the installed VPN service, named Routing and Remote Access. You can find this service from Start→Program→Administrative Tools→Service.

== About This Guide ==


<p>From  Start→Program→Administrative  Tools→Routing  and  Remote  Access,  please open  the  Routing  and  Remote  Access  panel.  Right-Click  on  “Routing  and  Remote Access”  on  the  left-side  of  the  panel,  please  select  “add  server”  to  add  a  VPN server.</p>

VPN (Virtual Private Network) refers to a computer and firewall with VPN capability that can establish a secure tunnel between the server and a client over the Internet. In the tunnel initiator (server), the user's private data is encapsulated and encrypted and then transmitted through the Internet; on the receiver side (client), the received data is unpacked and decrypted. VPN services are installed with Windows 2000/2003. This manual is based on the installed VPN service, named "Routing and Remote Access". This service can be found from <code>Start Menu - All Programs - Administrative Tools - Services</code>


<p>Right  click  on  the  added  server,  and  select  “Configure  and  Enable  Routing  and Remote Access”. If the Windows Firewall/Internet Connection Sharing (ICS) service is enabled, the Routing and Remote Access service cannot be enabled, and an ICS service  warning message  will appear. Disable the ICS service and redo  the above operation. After turning on Routing and Remote Access, the following configuration wizard will appear.</p>
== Routing and Remote Access Configuration ==


[[Image:vpnsol img02.jpg|370px]]
From <code>Start Menu - All Programs - Administrative Tools - [Routing and Remote Access]</code> open the Routing and Remote Access control panel. Right-Click on Routing and Remote Access on the left-side of the panel, then select Add server to add a VPN server.


<p>Select Remote access (dial-up or VPN) and click next to get into the next page. </p>
[[Image:vpnsol img01.jpg|500px|alt=routing and remote access main window]]


[[Image:vpnsol img03.jpg|370px]]
Right click on the newly-added server and select Configure and Enable Routing and Remote Access. If the Windows Firewall/Internet Connection Sharing (ICS) service is enabled, the Routing and Remote Access service cannot be turned on, and an ICS service warning message will appear. Configure the ICS service to allow the above operation, then redo the above steps. After Routing and Remote Access is enabled, the following configuration wizard will appear. In the Routing and Remote Access Server Setup Wizard window, under the Configuration step, select Remote access (dial-up or VPN) then click Next.


<p>Finish VPN installation. The next step is configuration.</p>
[[Image:vpnsol img02.jpg|500px|alt=choose remote access (dial-up or VPN)]]

Note

The following steps apply to Windows Server 2003 and Windows XP where relevant. For recent versions of Windows, the steps below may differ slightly.

About This Guide

VPN (Virtual Private Network) refers to a computer and firewall with VPN capability that can establish a secure tunnel between the server and a client over the Internet. In the tunnel initiator (server), the user's private data is encapsulated and encrypted and then transmitted through the Internet; on the receiver side (client), the received data is unpacked and decrypted. VPN services are installed with Windows 2000/2003. This manual is based on the installed VPN service, named "Routing and Remote Access". This service can be found from Start Menu - All Programs - Administrative Tools - Services

Routing and Remote Access Configuration

From Start Menu - All Programs - Administrative Tools - [Routing and Remote Access] open the Routing and Remote Access control panel. Right-Click on Routing and Remote Access on the left-side of the panel, then select Add server to add a VPN server.

Right click on the newly-added server and select Configure and Enable Routing and Remote Access. If the Windows Firewall/Internet Connection Sharing (ICS) service is enabled, the Routing and Remote Access service cannot be turned on, and an ICS service warning message will appear. Configure the ICS service to allow the above operation, then redo the above steps. After Routing and Remote Access is enabled, the following configuration wizard will appear. In the Routing and Remote Access Server Setup Wizard window, under the Configuration step, select Remote access (dial-up or VPN) then click Next.

choose remote access (dial-up or VPN)

On the Remote Access step, select VPN then click Next.

Appendix

Common errors upon VPN clients connecting to the server

Error Code Reason
800 Unable to establish VPN connection. The VPN server may be un-reachable, or security parameters may not be configured properly for this connection
619 In most cases, it is caused by the NAT-T function, used for clients to connect to the Internet, has been turned off, or a VPN that does not support NAT-T in GRE and PPTP protocol. To solve this problem, you can turn on the gateway’s NAT-T. If this error happens frequently, please change the gateway equipment.
721 In most cases, this problem is caused by the client system. If users are using Windows XP SP2, this problem may happen, and you can solve it through modifying the registry entry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\<000x> <000x> is the network adapter of the Satellite WAN port (PPTP) driver. In this key, create a new DWORD value, name ValidataAddress with value 0. If the configuration of the PPP protocol on the server is not correct, it will cause this problem as well.
718 Wrong user name or password when connecting, or authentication service error occurs on authentication server.
734 Normally caused by VPN configuration problems, such as PPP configuration, unsupported or poorly supported MPPE.
