Add PPTP or L2TP ports

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

To add PPTP or L2TP ports

  1. Open Routing and Remote Access.

  2. In the console tree, click Ports.


    • Routing and Remote Access/server name/Ports
  3. Right-click Ports, and then click Properties.

  4. In the Ports Properties dialog box, click either WAN Miniport (PPTP) or WAN Miniport (L2TP), and then click Configure.

  5. In Maximum ports, type the number of ports, and then click OK.


  • To perform this procedure, you must be a member of the Administrators group. As a security best practice, consider using the Run As command rather than logging on with administrative credentials. If you have logged on with administrative credentials, you can also open Routing and Remote Access by clicking Start, clicking Control Panel, double-clicking Administrative Tools, and then double-clicking Routing and Remote Access. For more information, see Default local groups, Default groups, and Using Run as.

  • On Windows Server 2003, Web Edition, and Windows Server 2003, Standard Edition, you can create up to 1,000 Point-to-Point Tunneling protocol (PPTP) ports, and you can create up to 1,000 Layer Two Tunneling protocol (L2TP) ports. However, Windows Server 2003, Web Edition, can accept only one virtual private network (VPN) connection at a time. Windows Server 2003, Standard Edition, can accept up to 1,000 concurrent VPN connections. If 1,000 VPN clients are connected, further connection attempts are denied until the number of connections falls below 1,000.

  • You cannot set the number of PPTP ports to 0. To disable PPTP, clear the Remote access connections (inbound only) and Demand-dial routing connections (inbound and outbound) check boxes.

  • When you increase the number of ports for WAN Miniport (PPTP) or WAN Miniport (L2TP) from less than 1000 ports to greater than 1000 ports, you must restart the computer to apply the change.

Information about functional differences

  • Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
