The official related documentation (docs.gl-inet.com) does not seem to be up to date.
Currently, I have one more required field to start the Wireguard server service, named “IPv6 Address”.
This field is not editable without activating previously IPv6 with NAT6 mode on the router first.
I can’t figure out what is the IPv6 address I should fill-in. The two IPv6 addresses of the router itself, displayed on the first “Internet” tab of the admin panel, are not accepted.
Any advice is welcome !
