Interestingly enough station bridge is now working, where earlier it was not until I switched it to station pseudobridge
Now I switched it back and it works fine.
For anyone wondering though, the difference between station bridge and station pseudobridge is:
Station Pseudobridge:
Normal AP connections do not use 4-address header information, and therefore source MAC addresses are lost (you need 2 for the radio MACs, and 2 for the src/dest MACs). Therefore pseudobridge does MAC NAT (for lack of better terms). So everything looks like it is coming from one MAC address.
Station Bridge:
This is only compatible with other wifi-qcom devices. It hooks to another device in AP mode and will create a 4-address connection. Therefore MAC NAT is not needed. The documentation is not clear about this at all, that one side needs to be in AP mode and the other side in Station Bridge mode.
From whatI can tell, this is pretty much equivalent to WDS on other wifi brands. Except somehow Mikrotik made it proprietary for wifi-qcom. I don’t know why, but this is what it is.
