When using SIM card in RUT240, the IP is always in range 10.xx.xx.xx, a private IP.

Using the same SIM card in IPhone, it gets an public IP, 80.xx.xx.xx... How come this is different?

I known that DDNS to a private IP do not work, and that is what I need.

Are there some settings I should look at?

Best Regards,

Martin C

I talked with my ISP provider (Telia) and they can't give me an public IP address. They recommend that I get a SIM card with Fixed IP.

So this is next step in the test.

Hello Martin,

To get public IP address you should enter APN which you get from operator.

Open the RUT240 WebUI and navigate to Network -> Mobile -> General. Enter APN and click save.

Hello Mindaugas

OK - great.. I tried this but and rebooted the RUT. It still gets the private IP,

These are the Mobile settings:

This is default APN which is defined on operator's website. Could you check your IPhone settings? Operator has sent it to your phone when you put SIM for the first time. You should apply the same settings to the router.
