Setting up WireGuard on a GL-iNet MV1000 via the Luci interface as the GL-iNet overlay is a bit to simplistic. Problem is after installing the packages, I do not have a key generate button in the GUI. Is there another package needed?
No, you just:
- generate the keys from the command line
- use keys you already have
- generate them elsewhere
Also, it appears you do not have official OpenWrt installed - feel free to ask your GL-Net support forum.
