I cannot get IPv6 to work with my TRB140 (FW TRB1_R_00.02.05.2). Provider is Telekom.
I tried with both their IPv4/IPv6 APN (internet.telekom) and their IPv6-only APN (internet.v6.telekom). "Use builtin IPv6-management" is set to "on".
With APN internet.telekom, I get an IPv4 address on the mobile interface, but no IPv6 address
With APN internet.v6.telekom, the mobile interface just keeps restarting.
Using the SIM card in an Android phone, both APNs work as expected.
What can I do to further investigate this? I found only one question which could have been helpful, there a test firmware was mentioned, but further communication seems to have been done via PMs.
(I bought the TRB140 because I had read on the forum that the TRB and RUTX devices would support IPv6 as opposed to the RUT devices, which might not. This is the question where someone mentioned the IPv6 support for TRB and RUTX devices: https://community.teltonika-networks.com/24835/how-can-i-config-telekom-de-lte-ipv6-to-rut955
