ICS and HomeGroup over cross-over cable in Windows 7 [How To]

image If you are using a cross-over cable (or known as P2P cable) to connect both Windows 7 PCs (other Windows client is possible) and wish to enable Internet Connection Sharing (ICS) and HomeGroup (function that specific to Windows 7 for easy file sharing), you are in the right place. Of course, a router (wireless or not) can easily get the job done, but why waste some bucks on the router while there is only 2 PCs available to communicate? Here I will show the components, steps and settings needed to enable both ICS and HomeGroup simultaneously over a cross-over cable.

Components Needed

1. 2 PCs – Host must be a desktop (because 2 LAN ports are needed); Client can be a desktop or laptop

2. 3 LAN ports – 2 LAN ports on Host, 1 LAN ports on Client

3. 1 Cross-over cable – Also known as P2P cable; Port configuration different from normal network cable

4. Windows 7 installed on both PCs – x64 platform tested

Step-by-step (Host)

1. Ensure the host PC has 2 workable LAN ports – One for internet connection source (eg. DSL), another for cross-over cable. Connect the cables. Connect the other side of cross-over cable to the Client PC.

2. Navigate to Network Connections (Control Panel > Network and Internet > Network Connections), select both LAN connections, right click and bridge the connection. For more information on network bridging, check here.

3. After both LAN connections are bridged, you will find there is a Network Bridge (icons below) in Network Connections window. (Don’t mind about the Network 2 in the screenshot below, it might be different in your case)

4. Right click on your Broadband dialer > Properties. Navigate to Sharing tab, tick on the first option “Allow other network users to connect through this computer’s Internet connection”. It will automatically allows the Network Bridge to share the internet connection. Once the setting is applied, there is a prompt saying that once the ICS is activated, DHCP will be turned off and the IP address for the Network Bridge will be configured to 192.168.137.1 (it might be different in your case).

5. Right click on Network Bridge > Properties. Double Click on TCP/IPv4 (as highlighted in below screenshot), and you will find the IP address was set to 192.168.137.1. Leave it as it is, then proceed to set the Subnet mask to 255.255.255.0, and Default Gateway to 192.168.137.10 (it can be different IP – it is an IP address for the Client PC). And you are done (for host PC).

Step-by-step (Client)

1. Access the TCP/IPv4 settings on the LAN connection in Client PC. Set the IP address for Client PC as 192.168.137.10 (as mentioned before, this can be different, but must be the same as the Default Gateway IP in Host PC), Subnet Mask 255.255.255.0, Default Gateway 192.168.137.1, Preferred DNS Server 192.168.137.1. (Update 16/07/2010: It would be better the DNS to be inserted with your ISP DNS Server addresses, or Google Public DNS 8.8.8.8 and 8.8.4.4.)

2. Once the settings are applied, the internet connection should be shared from the Host PC to Client PC.

How about HomeGroup?

HomeGroup is a new feature in Windows 7 that ease the sharing of files and printers between the home PCs.  If you have 2 Windows 7 home PCs connected using cross-over cable and you wish to enable HomeGroup function, well, definitely it is not a problem. The settings above should be allowing HomeGroup feature to be activated, and the HomeGroup can be created either in Host PC or Client PC. If you have no idea how to enable HomeGroup feature, PCPRO UK has a simple and complete guideline for it.

If you having problem getting the HomeGroup activated, please check that:

1. IPv6 is activated for both copy of Windows 7 (Host and Client)

2. The network location for LAN connections in both PC must be in Home Network (as screenshot below).

Author’s Say

The above guide should be helping you to enable ICS and HomeGroup simultaneously using only a cross-over cable for two Windows 7 equipped PCs. As mentioned before, the Client PC can be other Windows, but HomeGroup cannot be activated since it is an exclusive feature in Windows 7 only. Do let me know if you find my guide helpful for you, or you can always let me know if it doesn’t work for you. I will try to help if I am able to (though I am not a networking expert). Hope you enjoy the guide.

  1. This learning is very perfect. It’s work for me, very excellent.
    Thank you very much. Thank you very much. Thank you very much!

  2. I have a question if I may.

    I have 2windows 7 boxes currently using a satelite connection through a router. I have found satelite is hopeless and due to where we live the only alternative is dial up.
    I have installed a dial modem and it works far better than satelite with the box its installed in. I need a solution so both boxes can usethe installed modem.

    I used to have both connected with a crossover cable using an installed modem but with the current cofig the scond box wants to only use the router and satelite connection. o Ihave to delete the current nework to esablish a new network using the dial up modem?

    Thanks for any assistance

    1. Hi Dennis,

      Sorry for the extremely late reply. Hope you have had your problem solved. If not mistaken, you mentioned that your second computer is unable to get connected via the ICS? Do check the configuration, as I believe it will be the similar configuration, be it a broadband or dial up connection at the host computer. The client computer, should, by right, doesn’t need to do anything and get the shared connection from the host computer, if the configuration is done right. Do let me know if you still have difficulty in this setup.

      Rgds,
      Taylor
