How to disable port forwarding for VNC?

Question

SSH

Performed port forwarding to connect to the server

ssh -L 5901:127.0.0.1:5901 -N -f -l user server_ip_address

After that, I successfully went from the GUI to the server. After I closed the Reminna program, closed the SSH session, closed the console in general. And yet I can continue to log in to the server through Reminna! What kind of chaos is this? Why didn't everything stop and shut down? How can I close all this without restarting the client?
