Moin,

cngnat has to be turned off.

You have to pay a one time fee of 49,99€.

After that you have to change the APN and you are able to use port forwarding.

Hi schluej,

cngnat = Configuration NAT,  I suppose 

Do you have any info how the 49,99 service is called and where do I pay for it ?
And what do you mean by “changing the APN” ?

Thanks

cngnat = Carrier-grade NAT

Write the the 50€ are ok. Then a o2 Mod will activate the official IP for U.

I’m ok to pay one time fee of 49,99€. Please activate it

Thanks a lot for the info
I’ll let you know if I have any changes so far

@Your_e Changing APN means: change APN name from internet to netpublic 

Hi @Your_e, 

welcome to our English Community. 

It is nice that @Joe Doe and @schluej already helped you out with the suggestions. 

Now it is my turn to activate the public IPv4-address for you. Before I do that, I still need some personal data from you. Therefore, I wrote you a private message via @o2_Support. Please reply there to my request. 

Thanks a lot. 

Loving greetings,

Tobias

Hi @Your_e, 

thanks for your prompt reply at @o2_Support. 

I have just activated the public IPv4-address for you. 

As @Joe Doe already told you, please change the APN to “netpublic”. 

You will see the charge of 49,99 € on your next invoice. 

Additionally, I have ordered the delivery of the personal identification-code by letter to your contact address. You will therefore receive a letter in the next days. 

If you have any further questions, just feel free to contact our English Community. 

Loving greetings,

Tobias

Thanks a lot for the help and support. Will check if the updates took place and if it properly works. 

I suppose this will do the trick, but just correct me if I’m wrong:

1. disable NAT;
2. use  “netpublic” instead of “internet” (should I leave the other part as it is - “netpublic.eplus.de” ?);

@Your_e Only netpublic without suffix and without username / password 

Hi, and the Authentifizierungsart? None, PAP oder CHAP?

The APN Type ,I Think Dynamic is right?

@Your_e PAP

Hi @Your_e, 

wow! You got some help from @Joe Doe Thanks a lot. 

Did you succeed with these suggestions?

Loving greetings,

Tobias

Hi everyone,

Looks like the port forwarding works and it is opened for the dedicated device.

Nevertheless, I will proceed with more testing trough the week and will let you know if I encounter any issues.

Until then, I would say thanks a lot everyone for help and contribution

Best,
Your_e
