You need a specific way (repeater or bridge mode) and this is not tested
The idea is that only the wireless MACs are registered with each other, so
if you're sending traffic from a non-WiFi MAC to a non-WiFi MAC, you need
to encapsulate them. This is supported in the 802.11 standard, but not in
the standard "AP" or "client" configuration. This is what products called
"wireless bridges" do.
