IP Passthrough is not working

I currently have the M1 setup as my modem in front of my router.  But, my router is showing the public IP address is 10.x.x.x which is a private IP address.  I have the checkbox checked for IP passthrough in the modem's setting set to on.  Yet, I still get the 10.x.x.x IP address.  Any ideas?

    Is it causing issues? 

    It might have been your router changed its default ip address and doesn't change it back unless you force it.

    This might be perfectly normal depending on who the service provider is.

     

    EE in the UK assigns 10.x.x.x IPv4 addresses to customer WANs instead of using CGNAT ranges (which it also sometimes assigns). I don't think it's very considerate usage of 10.0.0.0/8 as it might clash with a customer's private network.
