Connecting Remote PC via JTAG doesn't work

Hello,

I have a remote PC (OpenSuse) that has Quartus on it.

I want to make it so I can program the FPGA Board that is attached to my local PC (Windows 10 with WSL Debian).

Local PC:

So the JTAG-Server is running on my local server.

Remote PC:

That means I have connection between these two PCs.

But Im still not able to establish a JTAG connection. I thought that maybe the firewall is blocking the communication so I did

"sudo ufw allow 1309/tcp"

or even "sudo ufw disable"

but nothing worked.

Help would be appreciated.

Best,
Atakan
