It's all up and running but I cannot access the bridge via its IP address when I am connected to it directly via ethernet. But I can connect to the bridge if I am using the main router's WiFi or through ethernet connected to that router.
When I used relayd I believe I had to use a random IP. Like the relay client is supposed to be transparent to the network. Maybe you need some extra masquerade rules?
I was able to switch to plain mac80211 wds and my life is a lot easier now.
(small hiijacking for a good cause) @Rampler@weedy could you please check the if this short wiki paragraph about relayd is correct and maybe add your configs too in the examples?
Relayd randomly stopped working and the clients connected to the repeater can't get an IP. The repeater can access the network and the Internet itself though.
Did a factory reset and the exact same issue.
Flashed a DD build and up and running straight away.
