i buy the RUT240 and create a DDNS from noip for connecting a IP camera.
I startet my project in Germany and it is working.
Now i have it in India and switch only the sim card (New provider Airtel).
APN Information i get from https://my.noip.com/#!/dynamic-dns
I talk with the provider service and they confirm this information.
As i want open my DDNS it show me an error.
I look by noip and they show me the right IP.
Then i thing it could be a block from the provider.
But the service told me. That isn't a provider problem.
My opinion is, that can only a Firewall problem.
But i don't see a setting problem.
Could you help me ?
I could give you a back up to get more information.
