How to install and Turn on a VPN Server
To install and turn on a VPN server, follow these steps:
1. Click Start, point to Administrative Tools, and then click Routing and Remote Access.
2. Click the server icon that matches the local server name in the left pane of the console. If the icon has a red circle in the lower-left corner, the Routing and Remote Access service has not been turned on. If the icon has a green arrow pointing up in the lower-left corner, the Routing and Remote Access service has been turned on. If the Routing and Remote Access service was previously turn on, you may want to reconfigure the server. To reconfigure the server:
1. Right-click the server object, and then click Disable Routing and Remote Access. Click Yes to continue when you are prompted with an informational message.
2. Right-click the server icon, and then click Configure and Enable Routing and Remote Access to start the Routing and Remote Access Server Setup Wizard. Click Next to continue.
3. Click Remote access (dial-up or VPN) to turn on remote computers to dial in or connect to this network through the Internet. Click Next to continue.
3. Click to select VPN or Dial-up depending on the role that you intend to assign to this server.
4. In the VPN Connection window, click the network interface which is connected to the Internet, and then click Next.
5. In the IP Address Assignment window, click Automatically if a DHCP server will be used to assign addresses to remote clients, or click From a specified range of addresses if remote clients must only be given an address from a pre-defined pool. In most cases, the DHCP option is simpler to administer. However, if DHCP is not available, you must specify a range of static addresses. Click Next to continue.
6. If you clicked From a specified range of addresses, the Address Range Assignment dialog box opens. Click New. Type the first IP address in the range of addresses that you want to use in the Start IP address box. Type the last IP address in the range in the End IP address box. Windows calculates the number of addresses automatically. Click OK to return to the Address Range Assignment window. Click Next to continue.
7. Accept the default setting of No, use Routing and Remote Access to authenticate connection requests, and then click Next to continue. Click Finish to turn on the Routing and Remote Access service and to configure the server as a Remote Access server.

How to Configure the VPN Server
To continue to configure the VPN server as required, follow these steps.
How to Configure the Remote Access Server as a Router
For the remote access server to forward traffic properly inside your network, you must configure it as a router with either static routes or routing protocols, so that all of the locations in the intranet are reachable from the remote access server.
To configure the server as a router:
1. Click Start, point to Administrative Tools, and then click Routing and Remote Access.
2. Right-click the server name, and then click Properties.
3. Click the General tab, and then click to select Router under Enable this computer as a.
4. Click LAN and demand-dial routing, and then click OK to close the Properties dialog box.
How to Modify the Number of Simultaneous Connections
The number of dial-up modem connections is dependent on the number of modems that are installed on the server. For example, if you have only one modem installed on the server, you can have only one modem connection at a time.
The number of dial-up VPN connections is dependent on the number of simultaneous users whom you want to permit. By default, when you run the procedure described in this article, you permit 128 connections. To change the number of simultaneous connections, follow these steps:
1. Click Start, point to Administrative Tools, and then click Routing and Remote Access.
2. Double-click the server object, right-click Ports, and then click Properties.
3. In the Ports Properties dialog box, click WAN Miniport (PPTP), and then click Configure.
4. In the Maximum ports box, type the number of VPN connections that you want to permit.
5. Click OK, click OK again, and then close Routing and Remote Access.
How to Manage Addresses and Name Servers
The VPN server must have IP addresses available to assign them to the VPN server's virtual interface and to VPN clients during the IP Control Protocol (IPCP) negotiation phase of the connection process. The IP address assigned to the VPN client is assigned to the virtual interface of the VPN client.
For Windows Server 2003-based VPN servers, the IP addresses assigned to VPN clients are obtained through DHCP by default. You can also configure a static IP address pool. The VPN server must also be configured with name resolution servers, typically DNS and WINS server addresses, to assign to the VPN client during IPCP negotiation.
How to Manage Access
Configure the dial-in properties on user accounts and remote access policies to manage access for dial-up networking and VPN connections.
NOTE: By default, users are denied access to dial-up networking.
Access by User Account
To grant dial-in access to a user account if you are managing remote access on a user basis, follow these steps:
1. Click Start, point to Administrative Tools, and then click Active Directory Users and Computers.
2. Right-click the user account, and then click Properties.
3. Click the Dial-in tab.
4. Click Allow access to grant the user permission to dial in. Click OK.
Access by Group Membership
If you manage remote access on a group basis, follow these steps:
1. Create a group with members who are permitted to create VPN connections.
2. Click Start, point to Administrative Tools, and then click Routing and Remote Access.
3. In the console tree, expand Routing and Remote Access, expand the server name, and then click Remote Access Policies.
4. Right-click anywhere in the right pane, point to New, and then click Remote Access Policy.
5. Click Next, type the policy name, and then click Next.
6. Click VPN for Virtual Private Access access method, or click Dial-up for dial-up access, and then click Next.
7. Click Add, type the name of the group that you created in step 1, and then click Next.
8. Follow the on-screen instructions to complete the wizard.
If the VPN server already permits dial-up networking remote access services, do not delete the default policy. Instead, move it so that it is the last policy to be evaluated.
