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?
Open a Command Prompt (on a Windows PC that’s connected to the internet, click on the Start menu, type “cmd,” and hit Enter) and type “tracert 8.8.8.8“ to see the traceroute to Google’s DNS server. If you see two private IP addresses listed in the first two hops then you have double NAT. If you see only one private address and the second hop shows a public address, then you’re all good
schumaku I got nothing. Now I'm traveling down a rabbit hole of research as I do some education :)
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!
