Double nat xr500

I have my ISP router (askey tcg-220) in bridge mode as a modem and the xr500 as a router, it’s posible that I can have double nat issues?, how can I test that?

That looks okay to me, one private address, one public.

Welcome to the Netgear Community, glad we have some new faces helping here!

 

I'm afraid, 10.74.0.1 is an RFC 1918 address, not a public IP, see below. It might be possibe that this is just used as an intermediate network however.

3. Private Address Space

   The Internet Assigned Numbers Authority (IANA) has reserved the
   following three blocks of the IP address space for private internets:

     10.0.0.0        -   10.255.255.255  (10/8 prefix)
     172.16.0.0      -   172.31.255.255  (172.16/12 prefix)
     192.168.0.0     -   192.168.255.255 (192.168/16 prefix)
