Flint 2 MT-6000 / IPv6 only /64 from provider

Technical Support for Routers

Hi,

i use a Zyxel NR7302 5G modem in Passthrough mode and it works okayish with a FritzBox.

Meaning:
IPv6 working and Wireguard on FritzBox with DDNS works and i can connect via IPv6 to my home network.

Now i have a new Flint 2 MT-6000 Router and i tried to get IPv6 working.

The thing is, the router somehow works, but not really works. For example the IPv6 DNS is not passed on and in the GUI it shows the correct IPV4 DNS from my provider but not the correct IPv6 DNS.

I know the whole thing is due to the fact that my provider only hands out one /64 subnet and the router must be part of that and can't pass on a another subnet (prefix delegation).

But how the FritzBox is able to deal with it and the Flint 2 not?

IPv6 at Passthrough mode in MT6000 is supported.

It's the IPv6 information provided by the primary router, which probably the MT6000 and FritzBox are different?

Can you send the IPv6-related information of both of them? To compare, including IP/Gateway/DNS, and preferably obtained by execute command: ifconfig.

Note: the IPv6 feature of VPN server in GL firmware is in the develop plan, now not support.
