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

With WireGuard VPN connections, devices in the remote network can be accessed via IPv4 as well as IPv6. However, internet access via the remote FRITZ!Repeater is only possible via IPv4; IPv6 internet services cannot be accessed. We are working on a solution and will make internet access via IPv6 possible via the remote FRITZ!Repeater in a future FRITZ!OS update.

With IPSec VPN connections, the FRITZ!Repeater can only transmit IPv4 data within the VPN tunnel. It is not possible to access IPv6 internet services or devices in the remote network over an IPSec VPN connection if they are only available via IPv6.
