I have a Unify Dream Machine and would like to connect it directly to the fiber network without using Interbox 4, thus avoiding double NAT.
I read that this is only possible with approved modems from Swisscom, but I have great doubts about which approved modems are also suitable for the Unify Dream Machine.
Is there anyone here who has experience with this and can help me with the process?
Thank you in advance
You can do it if you really want to, but objectively speaking it has more disadvantages than advantages.
What exactly bothers you about a double or multiple NAT, as is always used in a professional environment anyway?
If you actually have something that wouldnât work with a double NAT, we could certainly help here.

Hello, and thank you for your answer.
I donât have any problems with double NAT. However, I would rather avoid having so many devices.
I already have a 10GB RJ45 SFP+ for my Unify and it works fine.
If, as you write, there are major problems if you go straight, then I would like to stick with the current solution.
The problem is that at 10 gbs my router canât do bridge mode, only dmz.
Best regards
Thomas
Read through the thread here, it fits your question well đ

Ok, I just saw that youâre writing about the Dream Machine, without pro.
The only real difference between a router cascade with double NAT and a single router connected directly to the ISPâs backbone is approximately 0.3 to 0.6 milliseconds higher latency, which is still within the measurement uncertainty and can be completely ignored.
But what is lost if you do without a provider CPE is the clear separation of responsibilities between pure Internet access and operation of the internal network, which then brings clear disadvantages in any troubleshooting and also in possible support issues, because in the specific example you are now completely Youâll never be able to tell the difference without an Internet box, itâs Swisscomâs fault or itâs your own fault.
In a cascade it is always clear, because either the upstream Internet box is running correctly or it is not.
Another special topic in the UniFi environment is blue TV, which can always be operated directly on an Internet box, or âtaggedâ through a downstream network via VLAN, but then forces you to do the problems that occur very frequently in the UniFi environment without an Internet box Actually solving multicast problems directly within the UniFi network.
Conclusion: If at all I would only consider connecting directly to an FTTH provider with my own router if there were no additional provider services, such as: B. Landline or blue TV should be operated, so really only for naked Internet.
This is probably not the case for you, otherwise you probably wouldnât have subscribed to blue Internet at all đ

On the subject of Unifi and double nat, you can now switch this off with the current firmware even with an upstream router

And because it fits the topic, a second one that questions the whole thing đ

But I didnât turn it off on my IB3-UDMpro combination because, as @Werner already pointed out, I havenât noticed any deterioration in the ping values, I have a blue TV and the analog landline telephony is still fixed is part of our household.
And DDNS and VPN also work so easily, both externally and internally.
