Hello everyone

Topology:

Rasberry PI --> Internet Router Telekom Speedport --> Internet
Forwared port on Router to RAS: 55100

I've created an an DDNS Request from my rasberry pi with an update Line:

https://api.dynu.com/nic/update?hostname=moejoe.cx.org&password=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

The update itself Works the correct ip Address will be queried.

When someone tries to connect over this Port it doesn't work

I've also an other ddns Provider and these one works.

So what i have to change ? or may the constellation above doesn't work with your service ?

Your domain name needs to be using Dynu name servers below:

NS1.DYNU.COM
NS2.DYNU.COM
NS3.DYNU.COM
NS4.DYNU.COM
NS5.DYNU.COM

If the name servers are not changed, the IP address of your domain name may be updating correctly in Dynu's system but not over the internet.
