Enable IP Forwarding in Windows 2000


If you install multiple network cards (NICs) in a computer running Windows 2000
Professional there is no really convenient way to enable routing. Yet, if you
want the computers on the different networks to be able to talk to each other
you need to enable routing on the computer where the multiple network cards are
installed. Routing between networks using a software router only works when
routing Ethernet networks or Ethernet – USB networks. To route a 802.11b
Wireless network you must use an Access Point with a router. To enable TCP/IP
Forwarding use the following registry hack:

Hive: HKEY_LOCAL_MACHINE
Key: SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Name: IPEnableRouter

Type: REG_DWORD
Value: 1
