Hi!
I'm trying to replace my trusty tp-link wa850re with a tp-link re200, courtesy to this new port: Port to TP-Link RE200 (thanks guys!)
The wa850re (running OpenWrt 18.06-SNAPSHOT, r7827-b7e7d220e7) is set up as a wifi repeater with relayd, and I'm trying to do the same on the re200 (running OpenWrt SNAPSHOT, r12040-8df14c229c), following the wiki entry for relay configuration and using the wa850re config as a template.
The wifi part seems to work fine (repeater connects as client to main router and creates its own wifi, my laptop can connect to repeater wifi) - but dhcp4 doesn't work. If I set a static IP address on my laptop and connect to the repeater wifi, it can access the internet fine. But, obviously, I need dhcp working.
I've tried disabling the firewall but that doesn't solve the problem.
One weird thing I've noticed:
On the old (working) repeater, the mac addresses on wlan0 and br-lan are different while the macs on wlan0 and wlan0-1 (repeater client and ap wifis) are the same.
On the new (buggy) repeater, wlan1 and br-lan have the same mac, and wlan1 and wlan1-1 have different macs.
On the relayd wiki page, there's this note:
The most common problem is that the client router cannot pass the DHCP message between the main router and the client connected to the client router. Currently it seems to be the hardware/SOC limitation (related to MAC cloning?)
I'm not sure that's the problem (after all the device is meant to be used as a repeater), but of course it could be.
Has anyone else got the re200 running as a repeater? If so: how did you get it working / set it up?
Debug info below:
Here's the NetworkManager log on the laptop:

The main router (OpenWrt 18.06.1, r7258-5eb055306f) seems to get the dchp requests from the laptop, at least in the router's log I can see:

Installing tcpdump on the re200 repeater and looking at dhcp requests shows this:
