Hi, sorry for the trivial question … 
Three cAP AC will finally arrive soon and I am trying to figure out how to configure CAPsMAN.
There are no VLANs and all wireless clients connected to the cAPs will have to communicate with each other, so I have to use the bridge, right?
If I use Local Forwarding and Client To Client forwarding instead, wireless clients connected in cAP 1 cannot communicate with those connected in cAP 2, did I get it right?
Thanks
Right. But not for the reasons you mentioned. It’s because you want CAP clients to communicate with clients of the other CAP or LAN servers and transparent communication between any two interfaces (ethernet, wireless, …) goes via a bridge.
Wrong.
If you don’t select client to client forwarding, then clients of same AP won’t be able to communicate with each other (has nothing to do with other clients of other APs).
If you don’t select local forwarding, then all traffic of all wireless clients (of all APs provisioned with same datapath setup) will pass CAPsMAN, even if destined to another AP which is connected to same LAN or any other LAN member (e.g. wired NAS).
Thanks for your help 
One last thing escapes me, what’s the point of this configuration?
Why use bridge and local forwarding together?
I see it in many youtube guides.
I have tried and it is definitely a wrong configuration.
The local forwarding setting takes priority over the bridge setting.
It’s all clear now, thanks again for your help.
