Enabling IP Routing In Windows 2000.....

By default, IP routing is disabled. To enable IP routing, you must allow the computer to forward IP packets it receives. This requires a change to the Windows 2000 system registry.
When you enable the Routing and Remote Access service for IP routing, this registry entry is made automatically.

To enable IP routing

1 .From the Start menu, click Run.

2.Type regedt32.exe or regedit.exe, and then click OK.

3.In a registry editor, navigate to
HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\Tcpip \Parameters

4. Select the "IPEnableRouter" entry (by defining as value : 1 ) :

5. To enable IP routing for all network connections installed and used by this computer, assign a value of 1.
To do this in regedit.exe, right-click the entry, and then click Modify.In regedt32.exe, click on the wanted entry, click on Edit, and then click on the appropriate menu choice.

6.Close the registry editor.

It is required to reboot Windows 2000 for this change to take effect.
