local 802.11 ARP requests not forwarded

[slightlyunconventional]

firmware version: 3.23.8.0

My network topology is:

mesh
└ ki7kkm-mobile (LiteBeam 5 AC)
  ├ element (laptop)
  └ ki7kkm-services (server)

All links are wireless; the LiteBeam is running an 802.11 access point and the server and laptop are connected to its SSID.

When attempting to ssh directly from the laptop to the server, I get "no route to host" errors. However, I can ssh from the laptop to the LiteBeam, and then from the LiteBeam to the server.

tcpdump on the laptop and server reveals that the laptop is sending ARP "who has" requests which are never answered. The server never sees those requests.

I expected that the LiteBeam would forward the ARP lookups for the server, but that doesn't seem to be happening. I noticed that br-lan has the MAC address for wlan0 (70:a7:41:1f:c9:ec), but wlan0 is the mesh interface, which isn't part of br-lan. Should it have the MAC for wlan1 (72:a7:41:1e:c9:ec) instead?

I haven't worked much with bridges, so I'm probably missing something simple...

I upgraded to 3.23.12.0 and I no longer see this problem. I don't know if that's causation or correlation, but either way I'm closing the issue.
