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?

Sorry Alvarommb for the excursion....
plemans start reading here: https://en.wikipedia.org/wiki/Carrier-grade_NAT - as more and more ISP run out of public IPv4 routeable addresses, they assign either RFC 6598 (or even RFC1918 private IP addresses). It's like a phone number where you can't call the phone number, but can only dial-out. You will understand this easily - your know-how and assistance in this community is great!
