    It depends on your router. Generally privit subnets are not routable, but in practice, if you have "real" router, you can configure router table. It does nothing with Windows 7.

      You can enable IP routing in Windows 7 by modifying the relevant registry key.

       The IPEnableRouter registry entry:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\Tcpip\Parameters\IPEnableRouter

    Set registry entry to 1 (data type is REG_DWORD)

      This will enable IP forwarding on the workstation. However traffic will only move from one subnet to the other if the routing is set up correctly. It will "just work" if the router is the default gateway for both subnets.

    192.168.2 x  dg 192.168.2.254

    Win 7 router
    192.168.3.254  dg  blank
    |
    192.168.3.x   dg  192.168.3.254

    It gets harder if either subnet uses a different gateway. You need extra routing to get the traffic to the Win 7 router (and these routes are not set up on the router workstation itself).

      The Win 7 router can only forward traffic which actually reaches it! It can do nothing about traffic which goes to a different gateway.

    Hi,

    Before you want to consider Windows 7 as a router, you must make sure this computer is equipped with 2 network cards. One network card connect to 192.168.2.1, one connect to 192.168.3.1.

    There is an tutorial about how to make Windows XP as a router( It’s same with Windows 7), more information refer to the link below:
