OK we have a weird setup I know.. We create an SSH tunnel to our work network, then use RDP to connect to our workstations in the office. Our SSH client is setup to forward local post 1024 to our workstation on port 3389.
This works great with Remote Desktop Connection (mstsc.exe), but doesn't work with the Microsoft Store version of Remote Desktop.
Does anyone know why?
I cannot answer "why" but I can confirm the problem. I have captured network traffic and I see no response to initial SYN packet from Microsoft Store App. MSTSC and Store App send identical first packets for all I can tell. I tried to disable firewall on local Windows desktop which did not change anything. My only guess that App is using some different API than MSTSC to make connection so that ssh client does not see these packets even though they appear "on the wire".
