Question about Ubiquiti UniFi Cloud Gateway UCG-Fiber

Hello everyone, I am currently using the FritzBox 5590 Fibre and would like to switch to UCG Fibre. The FritzBox will then only function as an IP client for smart home DECT devices and as a mesh master for the three repeaters. I have the following requirements for the UCG fibre: PPPoE For authentication and dialling into the WEMAG network IPv4 & IPv6 Support for both Internet protocols DS-Lite Dual-Stack-Lite (IPv4-in-IPv6-Tunnel) DHCPv6 For automatic network configuration I have not yet been able to find any reliable information on whether DS-Lite (IPv4 in IPv6 tunnel) works reliably via PPPoE.
