Description
As i am trying to secure my VNC session using OpenSSH, i needed some help with ssh -vvv part.
Using the command ssh -vvv [email protected] -L 7934:10.31.128.23:5900 i have been able to establish a tunnel
C:\Users\w21821>netstat -aon | find ":7934"
TCP 127.0.0.1:7934 0.0.0.0:0 ABHÖREN 5488
TCP [::1]:7934 [::]:0 ABHÖREN 5488
After pinging my vnc Viewer on 127.0.0.1:7934, i get
C:\Users\w21821>netstat -aon | find ":7934"
TCP 127.0.0.1:7934 0.0.0.0:0 ABHÖREN 4676
TCP 127.0.0.1:7934 127.0.0.1:65501 HERGESTELLT 4676
TCP 127.0.0.1:65501 127.0.0.1:7934 HERGESTELLT 7028
TCP [::1]:7934 [::]:0 ABHÖREN 4676
This established Connection is not going through the tunnel.
Following is my debug Report

Can someone guide me is there anything wrong found in this debug or what else can i do to proceed?
Thanks!!
