PuTTY SSH Tunneling

This post explains how PuTTy SSH Tunneling can be easily used to bypass firewall rules blocking ports. Let’s say that we have the following setup where only communication via port 22 is allowed between two hosts:

Step 1: Open profile and load server’s profile

Step 2: Navigate to Connection->SSH->Tunnels and add new port as the screenshot below, then click Add

Step 3: Navigate back to Session and click Save. Then Open an SSH connection and log in the server as usual; as long as the putty window is open and connected, the client can connect to the server’s port 9098 via port 22 using settings (IP 127.0.0.1 and port 9098).

Hope this was helpful…
