Hi all,

Sorry, my Dutch isn’t great, so I need to stick with English for now. I’m taking lessons! 

I have an issue accessing a web server hosted on my local server. Today I decided to switch from the DSL Odido connection to the new Klik & Klaar option. I got the 5G router (Zyxel NR5307) and everything works just fine - huge speed boost!

I set up a NAT rule to test access to the network from outside. I started a simple web server on my computer, and set up the rule to forward requests on a given port to my computer.
 

This works. On a different network, I am able to access the webpage just fine. My friends tested for me, all on different networks themselves.

However, this does not work on my mobile phone, which also is using an Odido subscription. When I try to access the external IP and port on my mobile, it times out. Ping fails. My friend on Lebara mobile can access my IP just fine and see the simple web page.

So I am wondering. Is there a configuration issue on the Odido side that is preventing access to the resource? It’s weird, it works fine on any other network…

Dankjewel in advance for any advice!
