Note: This is not about WireGuard itself, but about wg-access-server, which “is a single binary file that contains a WireGuard VPN server and a web user interface for device management.”
WireGuard itself has supported IPv6 since the start
Ok, title changed to that from "WireGuard Access server now supports IPv6". Thanks!
Also of note is that this is a fork of wg-access-server from the looks of it.
Yes, it's a fork as the original project is dead for a year already.
We used the Upstream project for a while, but we were missing some features like IPv6, so we started this fork and added them ourselves, hoping it would be useful for a few others as well.
