WDS is not the LAN?

Hi,

I have a router RB750 with the Ether1 connected to the LAN 192.168.27.x and the Ether3 connected to the ap 10.5.50.x.

The 750 has the NAT rules ( port 8291 ) that allow at the software winbox to connect to the Erher1 to connect to the ap connected to Ether3.

An AP (AP1) is connected to Ether3 while others ap are connected through wds.

The winbox connects at AP1 but not to those connected via wds

Why? wds is not like the LAN?
