JSI Tip 2427. How do I enable TCP/IP forwarding in Windows 2000?.

By default, TCP/IP forwarding is disabled in Windows 2000.

To enable TCP/IP forwarding, use Regedt32 to navigate to:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters

Double-click the IPEnableRouter value name in the right hand pane. In the DWORD Editor, set the data value to 1. This enables TCP/IP forwarding for all network connections on this computer.
