Enabling VPN in RRAS Causes Connection Issues to Remote Networks

ID: Q243374

The information in this article applies to:

Microsoft Windows 2000 Advanced Server
Microsoft Windows 2000 Datacenter Server
Microsoft Windows 2000 Server

SYMPTOMS

RRAS does not forward packets after you enable Virtual Private Network (VPN).

CAUSE

When you enable RRAS, the Setup Wizard lets you choose one of these five options:

Internet connection server
Remote access server
Virtual private network (VPN) server
Network router
Manually configured server

If you choose one of these options RRAS is configured just for the functionality each option describes. If you select VPN server, you configure RRAS to accept incoming VPN connections. This does not configure RRAS to act as a router, and secures the interface you select by implementing filters that only accept PPTP or L2TP traffic.

RESOLUTION

If you want your server to be a VPN server and also act as a router, follow these steps:

In the Setup wizard, click Manually configured server.

After you enable RRAS, click to select the Enable this computer as a Router check box to manually configure it in RRAS server properties.

To accept PPTP or L2TP connections, right-click Ports in RRAS Manager, and then click Properties.

Click WAN Miniport (PPTP), and then click Configure.

Click to select the Remote access connections (inbound only) check box. Repeat steps 4-5 for WAN Miniport (L2TP).

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
