Hello @tgifch

You can only get fixed IP addresses with a business subscription: [https://www.swisscom.ch/de/business/kmu/it-cloud/business-network-solutions.html](https://www.swisscom. ch/de/business/kmu/it-cloud/business-network-solutions.html).

Greetings Samuel

I want to assign a static IP address, but I can’t find the device in the device list? So of course I can’t write in an IP address.

Under “Port forwarding” I was able to enter the device with the IP address and the port with the checkmark for “Allow automatic port forwarding”.

Hello @Durchschnittsuser

Did you connect the device directly to the Internet box? Do you see the device after restarting the Internet Box?

Greetings Samuel

Hello Samuel

It has been resolved in the meantime, thank you. However, I haven’t tried the tips above. Best regards!

The DMZ function is not available (message on my Internet Box2, which no longer allows me to print and scan)

@PAG First of all Hi

In Expert mode the DMZ function reappears as if by magic!

Cordialement

What does “Important: Each static IP address can only be used once.” mean?

I guess it’s implied that it means simultaneously

I’m a bit lost right now. I made a device/sensor that I provided with a fixed IP (192.168.1.210), it worked perfectly, a day later it is still connected to the router, but there is no longer any communication with other devices. Since I can no longer reprogram the part and burn in a different IP, I made a new one, programmed it with 192.168.1.20, and it works.

Now I have two absolutely identical devices, both connected to the network, the one on.210 doesn’t work, the one works on.20.

Now to my actual question:

Is there any reason why the IP 192.168.1.210 shouldn’t work as a fixed IP? The DHCP range is .101-.200, so that shouldn’t be a problem…

I’m happy for any tips.

@Lieffitha90

Off the top of my head I can’t see any reason for this.

Have you ever reset the router with the staple?

But first, save the config locally on a PC and, if necessary (if you have a lot of individual definitions in it) and an initial test with the missing IP has been carried out, restore it again afterwards.

@Filipe Madureira

What does “Important: Each static IP address can only be used once.” mean?

It means that each IP address can be uniquely assigned to only one device at a time.

in practice you can use an address an indefinite number of times, but you can assign it to only one device at a time, this therefore allows you to reuse unused IP addresses or adapt new devices to the existing network.

the network ideal is that each device has its own UNIQUE and static network address, and this solves the vast majority of problems.

I was able to solve the problem with an update of the IB to the beta release 10.03.50.

I would like to open the ports on my router but it tells me that I have a non-public IP address so I can’t do it…help!

@Schiezauzieng92 can you check which IP address you use to browse the Internet?

The only problem with this function is that devices that are no longer in the network and have been solved continue to hang around in the IP reservation.

For example, I replaced my cell phone, which had a static address. Now I wanted to assign this static address to the new one, but the Internet box firmly claims that the IP is reserved (of course I deleted the device in the Internet box in advance)

The Swisscom hotline can’t or won’t help me with this, either you don’t call back and if you follow up again you’ll be treated rudely… Please solve this problem or provide assistance

@gl89

During a hard reset, an Internet box also forgets the previously assigned IP addresses.

Your problem can be solved with the following process:

- Briefly check the current configuration of the IB for the desired values, then save it locally on a PC

- Hard reset the IB during operation using a paper clip or SIM tool

- After restart, restore the CFG file from the PC and check the functionality, if necessary, re-register the router

- then adjust the IB settings again to new desired values ​​and save the config again on the PC for future use

Thank you SO MUCH for your answer. It almost sounds like I would have the solution after months.

But one more question before I sprint off and begin. Is the currently saved static IP also backed up in the configuration backup?

Because smart home with few devices…

@gl89

see here, yes, they are backed up.

@kaetho @Werner Thank you very much!!!
