CM700 ethernet port with switch

I'm considering replacing my current cable modem with the CM700 Netgear modem/router. This model has one gigabit ethernet port.

 

The wireless router is an R7000 set up in AP mode. That router will connect to the modem/router via an existing ethernet cable from the other room.

 

I also need to connect a few devices (including an NAS storage device, a laptop and a printer) to the network via ethernet. I would like to attach a separate ethernet switch to the modem's ethernet port and have everthing connecto to that switch.

 

Essentially, it will looke lie this:

 

Internet -> cable modem -> ethernet switch in modem's ethernet port <- (NAS, printer, laptop, wifi router from other room)

 

Will this be possible? 

 

I appreciate any assistance.

 

Thanks in advance.

    Hi,

     

    we strongly recommend you NOT to do it. It may not even work.

     

    Reasons:

    1. ISP ONLY allow 1 IP unless you are business account. Even if you have business account, you will only 5 IPs.

     

    Correct way to do it it

     

    Comcast --> CM700 --> Router ----> TV

      Comcast --> CM700 --> Router ----> ANY wired or wireless device..

       

       

      OR 

       

      Comcast --> CM700 --> Router ----> switch --> ANY wired or wireless device..

    You'll want to connect the R7000 to your CM700, and of you're trying to bridge from your modem to another room wirelessly, add an access point there. The modem doesn't have routing abilities and if it did I think you'd have issues with multiple IPs.

    I can vouch for the CM700/R7000 combo, works great for me with gigabit service.
