Does the FRITZ!Box transmit IPv6 network traffic over VPN?

The FRITZ!Box can establish VPN connections (IPSec, WireGuard) over both IPv4 and IPv6. This means that VPN connections can also be established if the FRITZ!Box is operated on an internet connection with Dual-Stack Lite (DS-Lite).

However, the FRITZ!Box can only transmit IPv4 data within the VPN tunnel. It is not possible to access IPv6 web services or devices in the remote network over the VPN connection if they are only available via IPv6.
