Accessing MB8600 Configuration page through r7000

Can anyone give me the secret sauce that will enable me to reach a Motorola MB8600 login page of the modem attached on my WAN port on the router from a device on the r7000 LAN?

 

R7000 is configured for Class B at 192168.x.x with it's own address at 192.168.0.1.

 

Motorola says its at 192.168.100.1 on a sticker on the bottom of it.

 

Router is not configured to login to the ISP.

 

I had the same problem when it was configured for a Class C LAN at 192.168.0.1.

 

I am unable to ping 192.168.100.1 either.

 

There was a suggestion that I configure my LAN at 10.x.x.x and then the router will forward it thourgh the wan port, but this is a pain in the butt, so if there is a way I can get this to work without doing that, I'd rather.

 

If I plug directly into the modem port with a windows PC, it's fine.

       A router like an R7000 has two interfaces.  You mean its (not "it's")
    LAN interface?  Why "Class B" (other than to cause problems like this)?

     

       "192.168.0.0/16" tells the R7000 that "192.168.*.*", including
    "192.168.100.1" is on its LAN.  Assuming that your MB8600 is actually
    connected to the WAN/Internet interface of the R7000, that would seem
    to be misleading.

       Same problem, I'd say.

       Perhaps, but that (default) configuration would have had a chance of
    working.  I'd return the R7000 to its default configuration (a settings
    reset might be the safest way to be sure), and start again.  Whatever
    problem you might have had, changing the R7000 LAN subnet mask is not
    the cure.

           In case you missed it, "192.168.0.0/16" can't work.  I know nothing
        about what you did before you got creative.  Look for "I'd".

         

           None of what you posted about the original ("192.168.0.0/24")
        configuration is a useful problem description.  It does not say what you
        did.  It does not say what happened when you did it.  As usual, showing
        actual actions (commands) with their actual results (error messages, LED
        indicators, ...) can be more helpful than vague descriptions or
        interpretations.

         

           Visit http://netgear.com/support , put in your model number, and look
        for Documentation.  Get the User Manual (at least).  Read.  Look for the
        LED descriptions and "Troubleshoot".

    Why do you want to do this?

     

    There isn't much that you can do to a modem's settings. You can't even change the firmware on a cable modem, because that is the ISP's prerogative. Most of the useful controls are done on the router.

     

    When a modem sits in front of a router the normal procedure – as described in the manuals – seems to be to disconnect from the router and plug directly into the modem. Then you can use its own IP address.

    That's about it.

     

    Messing around with IP addresses as you are is probably doomed to fail. You are trying to break how these things work. In the process, you may be making life more difficult for yourself with things that you can control.

     

    Then again, if you explained want to tunnel into the modem, someone may have a solution.
