Problems with Internet Connection Sharing (ICS), Windows Media Center, & Xbox 360 as Media Center Extender

Okay here is the problem. I have two networks connected to my Windows 7 Pro Media Center; one has internet (and is gigabit) the other doesn't (and is 100Based-T). I have a Media Center Extender and an Xbox 360 that I use as another Extender.

All works well until I try to share my internet connection between the two networks using Internet Connection Sharing. After enabling sharing the Xbox 360 can no longer find the Media Center no matter what I do. Disable ICS and everything is great again. Is there a work around to this? I need to share the internet with the other network, but I also need to have the 360 be able to connect.

I tried bridging the networks, but that only works until the next reboot and then the bridged connection has to be repaired for things to start working again.

    SOLVED:

    Follow these steps to successfully connect your Xbox 360 to your Windows 7 PC:

    ON YOUR PC:

    -Enable ICS by navigating to your network adapters and right clicking on your incoming wireless connection and go to its properties. From there choose the "Sharing" tab then choose both check boxes. Next we will enable port mapping and open up the xbox live ports. Choose setting under the sharing tab and click on add. From here you can input all required ports to connect to xbox live. You can find out more about port mapping by clicking the link below:

    (Note that port forwarding will only work if you open the ports on your router as well as your computer. So be sure to do so prior to connecting to xbox live.)

    ON YOUR XBOX 360:

    Navigate to the following:

    System Setting >> Network Settings >> Wired Network

    From here go to: Configure Network >> Additional Settings; and choose "Restore to Factory Defaults"

    Now choose "Basic Settings". From here input the settings below:

    IP Settings:                        Manual

    IP Address:                       192.168.137.2

    I assume that you've enabled Internet Connection Sharing on the gigabit Internet connection.  That automatically assigns an IP address of 192.168.137.1 to the Windows 7 Media Center's 100Base-T network connection and enables a DHCP server for the other devices on the 100Base-T network. 

    Configure the Xbox 360 to obtain an IP address automatically, or assign it a static IP address in the 192.168.137.x range.

    I know this is way late, but i just became a member just to post this.........Did you ever get this working? I think the key is in the public network settings like steve winograd pointed out. This worked for me after a week and a half frustration. The weird thing is that I could get it to connect initially, even though blocked in firewall.........?

    Hi Douglas,

    You may have already tried this, but running ICS and the second router is likely causing a conflict.

    ICS provides DHCP on that eth1 adapter, and the router is probably running DHCP as well.

    I suggest disabling the second (eth1) routers DHCP service to see if the issue resolves.
