I am trying to configure a new RUT950 modem but the IP address shown is not the real one - which means dyndns function won't work and I cannot connect to it from the internet. When I connect it to a laptop and use check-my-ip I can see the real IP address. I have another RUT950 (older version) which I use with the same sim-card and I do not get this problem. It seems like it manufactures some proxy addresses inside the modem - was the explanation I got from a technical friend. Any ideas?
