Windows 7 setup routing between 2 networks


Situation:


               | access point | wi-fi     |   my machine |           | 2-nd machine |
| 192.168.1.1 | --------- | 192.168.1.37 | Ethernet | |
Internet ---- | 76.77.15.87 | | 192.168.0.1 | --------- | 192.168.0.2 |

I have 2 computers:


The 1-st is connected to the Internet through wi-fi interface. Network: 192.168.1.0/24 default gateway: 192.168.1.1 (IP of the wi-fi access point). It works.


Now I have another machine, connected to mine through the Ethernet interface. Here I have a second network with 2 machines: 192.168.0.0/24:



  1. mine 192.168.0.1

  2. other machine: 192.168.0.2 default gateway 192.168.0.1


ping between the machines works. ping google.com on the 2-nd machine doesn't work.


Now I need to setup the route between the internal and external networks on my machine.


I don't know, what default gateway should I setup on 192.168.0.1 machine for 192.168.0.0 network, because my machine is the default gateway for this network. I tried


route add 192.168.0.0 mask 255.255.255.0 192.168.1.1

but it doesn't work.

Answer



Your route statement isn't what you want. The 192.168.1.1 router isn't the gateway for the 192.168.0.0/24 network (which is what your route statement says-- it's flat wrong).


You'll want to place a route on the 192.168.1.1 wireless router to give it a route to the 192.168.0.0/24 network via the 192.168.1.37 PC.


You'll also need to enable IP routing on the Windows 7 PC to get it to forward packets.
