I tried to connect to the Telekom-APN internet.v6.telekom with the following credentials to get an IPv6-address assigned to my RUT955 with firmware version RUT9XX_R_00.06.077.
APN Name: Telekom Internet IPv6
I disabled "Use IPv4 only" in the mobile section and enabled "IPv6 Support" in the administration section. I tried with QMI and PPP with PAP and CHAP, but unfortunately nothing seems to be working.
I know the question is very similar to this one https://community.teltonika-networks.com/24835/how-can-i-config-telekom-de-lte-ipv6-to-rut955. However, in my opinion, it has not yet been properly answered, or rather, according to the answers there should already be a firmware that solves my problem. But I haven't found anything yet and it doesn't seem to work with the current firmware. I therefore ask for your understanding.
I would be grateful for any kind of help.
