    a.

    In the OS's that needs to have web (internet) access use the ethernet cards built in mac address.

    In the OS's that need to have no web/internet access, set the mac address to a different value.

    On the router you should be able to restrict/assign different IP address based on MAC address, then set router to disable outgoing packets from restricted IP.

    OR

    b.
    Unplug the machine from the router when booting the restricted machine.

    Think for a few moments there blink... Why do you suppose I posted a screenshot of my modem page?

    a.


    In the OS's that needs to have web (internet) access use the ethernet cards built in mac address.
    and do what with it?
    In the OS's that need to have no web/internet access, set the mac address to a different value.
    set the MAC address where?

    This is the wrong answer for what I ask. This will take the subject OS NOT ONLY off of the WEB, but also off of my NETWORK LAN. That is not my objective.

    You DO know that modems are on the WEB [OUT]side of routers - correct?

    OR

    b.

    Unplug the machine from the router when booting the restricted machine.
    This is wrong also. This will take the subject OS NOT ONLY off of the WEB, but also off of my NETWORK LAN. That is not the objective.
    I tried to make clear, with the picture AND text, that I want to set the MODEM - at the modem page - to restrict 1 OS of a multi-boot machine from WEB access.

    Anybody help out here?

    It looks like your modem is a combination modem/router,
    because it has options to configure NAT and DHCP.
    These are typical router features. You didn't mention
    whether you have another router. I assume you don't,
    since it would be redundant.

    The suggestion about MAC addresses is not invalid, just
    a bit hard to grasp and implement. In the end, your modem/router
    may or may not be able to do this.

    The MAC address can be spoofed by the OS. One OS would
    be allowed to work normally, but the other would be configured
    to "lie" to the modem/router, sending a different MAC address.
    (I am not sure where you configure this)

    You would have to study the modem/router's configuration
    for security or content filtering options, and see if it could
    then prevent the one OS from connecting, based on MAC
    address.

    It may not have this feature. It probably can be configured
    to give a different IP address to the two Operating systems,
    but that may not be what you want.

    You may have to fall back on to the solution of configuring
    the OS on the computer to not go on the web, using a firewall.
