Hi,

I would like to request the addition of IPv6 support for WireGuard.

IPv6 adoption has increased significantly, doubling from 2020 to 2024, and now reaches approximately 75% in countries like Germany and France [1].

Notably, most fiber and cable connections in Germany are now behind Carrier-Grade NAT (CG-NAT), making it impossible to establish a VPN connection without IPv6 support.

To overcome this limitation, I have had to deploy a consumer-grade router (AVM Fritz!Box) in front of my professional Omada setup to facilitate VPN connectivity—an approach that undermines the efficiency and intent of a professional networking environment.

Implementing IPv6 support in WireGuard would greatly enhance its usability in regions with extensive CG-NAT implementation, streamlining secure connections for many users.
