Before you change, u used DSL?
I think U need a public IP. With mobile connection you have CGN. U can get a public IP from o2. Price is 49,90€.
With a non public ip the smart dns is unable to identify U!
Hi. Thanks for your answer. Is a “public IP” the same thing as “static IP”?
No. Static is always the same. Public IP is what you need for your smart dns.
The smart dns needs your „public ip“ to know that you are allowed to use the dns server.
So normally you tell the service i have IP xxx.xxx.xxx.xxx and you could use the dns.
With CGN you know only a private IP e.g. 10.xxx.xxx.xxx because you are sharing an IP with other users,
But the smart dns service get a request from the shared IP, so no access for you.
With public ip the ip U get is „you own“ IP and the dns service let pass you dns request.
So you have to tell you smart service every time (24h) the IP change the new IP address.
But that should be the same with a dsl connection.
Hi @Chrislan45 ,
welcome to our community 
Did the information from @schluej help you or are there any questions left open?
Kind regards

Not really. I am unclear as to whether paying 50€ for a ‘public’ DNS address would solve the problem. I am also generally unimpressed with the connection speeds offered by the Homespot box and am actively exploring reverting to traditional router. I am awaiting a callback from O2.
That’s not a public DNS. It is a public IP, that is needed to authenticate against your DNS Service.
Hi @Chrislan45,
as @schluej explained, these are 2 different things.
We can do it the same way: We set you the public IP, and if it doesn't work we change it again. There will be no costs for you. What do you think about it?
Kind regards
Larissa
OK thanks. This sounds very reasonable. I thought there was a 50€ charge for the IP address? If there isn’t, then please go ahead and let me know what I need to do? Thanks.
Hi @Chrislan45 ,
there is a one-time charge of 49.90 EUR for this. However, if the desired success does not occur within 14 days, we will take back the change and refund the 49.90 EUR. Please contact us for the setup and your agreement and also if the change does not work as expected.
Kind regards
Larissa
This seems like a plan 
. Please go ahead and make the change and charge. I understand that this will be on a trial basis (for 14 days) and that if it doesn’t work you will refund my money. Please can you reconfirm this by email? Thanks.
Hello @Chrislan45,
we don’t send confirmations by email. Is the assurance here in the public community not enough for you?
As you wrote, we will refund the charge if you are not satisfied with it. You can always contact us here for any complaints 
Please let me know if you want the public IP to be activated or not.
Best regards
Giulia
Yes, please go ahead. Thanks.
Hello @Chrislan45,
I have activated the public IPv4 for your SIM card now. In order to use it, please change the APN from “internet” to “netpublic” in the settings of your home spot.
Please let us have your feedback if this has solved your issue.
Best regards
Giulia
please change the APN from “internet” to “netpublic” in the settings of your home spot.
I’m sorry, I don’t know how to do this :-(
Hello @Chrislan45,
We have a guide here that @Joe Doe wrote for us: Tutorial: Öffentliche IP (Nat Typ 2) beantragen und Einrichten im o2 Homespot 2
Sorry it’s in German only. You can skip the first part and start by login on http://192.168.1.1/ or http://home.spot/ and got to “Netzwerk” and “LTE”.
Deactivate Auto APN and click on “Bearbeiten”.
Now you can enter “netpublic” under Profilname and APN, Authentifizierungsart PAP and IP Typ IPv4. Save (Speichern) and reboot your homespot.
Please let us know if you have any further questions.
Best regards
Giulia
Hello @Chrislan45,
do you have feedback for us if this solved your problem? For any questions, please let us know and we will be pleased to help you

Hi Giulia. Unfortunately, switching to the public IP address has not solved the issue – I’m still having to manually reactivate the IP address every time i use the Smart DNS connection. Given that it isn’t working, please can you refund the setup fee? I’d also like to explore the option of upgrading my contract and reverting to a traditional DNS router. Please could you give me some guidance on how I might do this? Many thanks for your continued support.
o2 only offers the 2 DNS server addresses. All other solutions are neither supported by o2 nor offered in any way.
Maybe there are alternative solutions for BBC etc. like

You can watch and record the British channels
Hello @Chrislan45,
the setup fee will not be invoiced, sorry this wasn't a solution for you.
As you have already contacted our customer service for the change to a DSL contract, is everything cleared already?
If you have further questions about this, please let us know.
Best regards
Giulia
Hi Giuilia,
Thanks for getting back to me and confirming that I will not have to pay the public IP address setup fee.
As you say, I have already decided to switch back to a conventional DSL Router and hope that this will resolve the issue.
I am still waiting to hear back from the email address they gave me (impressum@cc.o2online.de) to confirm the cancellation of my existing contract.
Thanks again for all your help,
Chris
The mail address is not suitable for support and contract processing! Your concerns are unlikely to be processed there. Please use fax or letter for important contract matters such as early termination.
Hello @Chrislan45,
your cancellation has already been confirmed for May 6th, 2022
Please let us know if you have any questions, also regarding the activation of your new DSL connection.
Best regards
Giulia
For what its worth, I still haven’t received the new router even though the new contract was confirmed on 25 April. The technician came today and verified the phone connection but I can’t use the service because I don’t have a router. Also, the German customer service number is almost unfit for purpose. It’s virtually impossible to get past the virtual assistant. Seemingly endless unhelpful robotic loops end with “Would you like me to send you a confirmation email or SMS?”, then “Thank you, goodbye!” Why on earth is it so difficult to get to speak to a real person?
Hello @Chrislan45,
I am sorry that your router was not ordered with your DSL contract and therefore has not been sent to you in advance. Meanwhile you have contacted our customer support and they have sent it by DHL. Have you received the email with the tracking code?
Please let us know when you have picked the package up and if everything went well with the set up of the router.
Best regards
Giulia
