Thanks for the quick reply, see mine below...

 

IP Pass thru on the ISP modem is not needed nor recommended if you have the Orbi RBR in AP mode. If your in AP mode then there is no firewall present if your using IP pass thru on the modem. You can change the Orbi to router mode then continue to use IP Pass thru.

Gotcha, thanks for this info. I've changed my Orbi router mode and kept my ISP modem in IP Pass thru.

 

 

Then you can also change the RBR IP addressing scheme as well.

So this is where I need help I think... Is there a recommended way to do the above and how is that done? Since putting the Orbi in router mode I can now get into the internet settings (see attached). I have not changed anythign there yet.

 

 

Thanks again.

For that, WAN side that IP address comes from the ISP modem. You can change what the RBR gets from the ISP modem there. I'ts best to leave this section Dynamic...

 

Look at the Advanced Tab/Home and look at the Internet secion on the right side of this page, what IP address is listed here? You may see a ##.##.###.### listed here or maybe a 192, or 172 or a 10 IP address here.

    Not sure I follow this... How do I change what the RBR gets from the ISP? Is that under the WAN setup tab? Or WAN prefence button?

    The IP address in the Internet Port section is a 192 one.

      You can change that ON the ISP modems web page. 

      Are you looking to change the 192. address to something different on the WAN side or you wanting to change the IP address of the LAN side. These are different sections.

           No, it really doesn't.  If your "the ISP modem" is acting as a simple
        modem, then your router's WAN/Internet IP address comes _through_ the
        modem, _from_ the ISP.  You have no real control over the
        external/public address which your ISP provides.

         

           In some cases, if you change the MAC address of your modem, or the
        MAC address of the WAN/Internet interface of your router, then you
        _might_ persude the ISP to grant a different address, but you can't
        _force_ your ISP to do anything.

           Still true.
