There is another limitation in the “QR settings” section of the wireguard menus, the “Peers allowed IPs” field is limited to All IP4 (preselected) All IP6 (preselected) and the local lan (not preselected).
The wg config file derived from the QR code must be manually edited to add others IP/networks if more networks are needed.
And while at it don’t use 0.0.0.0/0 nor ::/0 instead use 0.0.0.0/1 + 128.0.0.0/1 + ::/1 + 8000::/1.
Thank you for your suggestion. The R&D team has decided to add an option in the WebUI to specify custom networks (and split LAN to IPv4 and IPv6), similar to the example shown here:
