Manage MT behind a MT with Hotspot remotly

RouterOS General
1

Hello,
I have two hAP lite. One is configured as hotspot and a VPN Client. I can remotly Access this MT over tunnel address.
The second MT is connected over wds to the first. All Interfaces are bridged.
From hotspot MT I can ping the second.

Hotspot-MT:
LAN/Wifi-Bridge: 192.168.192.1/24
VPN-Client: 10.8.3.1/16

WDS-MT:
LAN/Wifi-Bridge: 192.168.192.20/24

On my PC adding route:
route add 192.168.192.0 mask 255.255.255.0 10.8.3.1

I can’t manage the second remotly.

Any idea

Remote router must also know destination of client’s subnet. Run traceroute to see where exactly to look for the problem.

From the MT behind I can ping the VPN-Server 10.8.0.1 and the Windows Client 10.8.0.2.
I think, I have no Need to add a route. The problem is must be the MT-Hotspot.
