How to Tunnel Remote PC's Port with heavy firewall to local machine

[nithi2023]

I have a remote server running Win10 from which I need to access one port (RDP) from my local laptop. Unfortunately, Remote Win 10 is heavily firewalled (zscaler). Only HTTP / HTTPS / WS is allowed on 443/80.

Please help me setting up wstunnel in that Win10 machine so that I can access that remote port in my laptop. I can run the wstunnel.exe in that Win10 machine.

Hello,
What have you tried ? It seems standard setup.
Just start tunnel with TLS on the server wss://0.0.0.0:443
on client side wstunnel -L 33891:localhost:33891 wss://windows10ip/host
on do a rdpclient on localhost:33891

Hi @erebe ,

Thanks for the reply.
Its not a standard setup. I will explain in detail about what I am trying to achieve.

Windows 10 - Remote Computer which has no public IP. It can contact Internet only through HTTP & HTTPS Port (80 & 443) due to heavy firewall restriction. Even SSH connections (to port 443) are dropped if try reverse tunnel a local port to my server. I don't have admin access. I am user with before said restrictions.

Ubuntu Server - with Public IP say 12.23.34.56 and can run anything. It can be used as relay if necessary.

My Local Laptop - Connected to internet. It has full access to Ubuntu Server (Can access SSH and other Ports).

I am trying to connect to RDP from My Local Laptop to Windows 10.

I can run wstunnel on Windows 10.

Lot of online help says, I can do it with reverse tunneling a port. But, I can't achieve through reverse Tunneling as SSH connections are dropped by Firewall.

Is it possible to achieve this with help of wstunnel ? Your help is much appreciated !!

You should be able to do it with wstunnel + ssh

1. Ubuntu Server : Start a wstunnel server with tls (wss://) or if it works without do it in plain ws://
2. Windows 10: start wstunnel client to contact the ubuntu server and make it target its ssh port (-L 2222:localhost:22)
3. Windows 10: start a reverse ssh tunnel throught the tunnel of wstunnel (ssh -R 33891:localhost:33891 localhost -p 2222)
4. now you have on yur ubuntu server a port that listen for rdp connection
5. on your local laptop do a simple ssh -L 33891:localhost:33891 ubuntu_server
6. start rdpclient targeting your local machine

You can even skip the ssh tunnel on 5, if you enable enable your reverse tunnel to listen on public interface
