I have a network managed by a Mikrotik router and an OpenWRT AP in it. AP acquires its IP by statically binding DHCP, i.e. 192.168.5.149. OpenWRT AP's settings are default, WAN-LAN, and double NAT, so WiFi clients get IPs from the range 192.168.1.0/24.
I'd like to avoid the LAN zone in OpenWRT, so my WiFi clients get DHCP offers from the Mikrotik router (192.168.5.0/24) directly. I tried to associate the WiFi interface in OpenWRT with the WAN zone, but the client does not get a DHCP offer at all.
Since this is pretty much a simple requirement, is there any guide I can follow to accomplish this?
