I have installed Wireguard on a Xiaomi 4A Gigaibit which is configured as OpenWrt Dumb AP.
The tunnel is working and I can ping or access LuCI on OpenWrt Dumb AP (192.168.0.2) but can't ping ISP router (192.168.0.1) or any other device on LAN.
It works well when the AP is configured as router.
Thank you very much, now it's working.
I have no WAN intefrface.
LAN and Wireguard interfaces are in the same firewall zone and masquerading is enabled.
Could you please explain the theory behind this???
