Gateway Mode AP and "HA" for branch office

[SmallPotato]

Hello, I would like to confirm what is the Slave unit behavior on Gateway Mode unleashed AP design.

Can I have a design like this and when the Msster AP is dead, will the slave unit pick up all config even those port forwarding?

Hi @SmallPotato 
If the Master is in Gateway mode and goes down for some reason, then the Member AP will NOT take over as Master Role. This is not supported in the Gateway mode.
You will have to re-configure the new Master and set it up in Gateway mode.
