How to Connect to VNC Server Using SSH Tunnel With Putty and Port Forward

How to Set up SSH SOCKS Tunnel for Private Browsing Linux 電腦普遍沒有 UI 顯示而採用 SSH 這類的遠端管理方式，這篇介紹的是連到 SSH Server 後以此為跳台瀏覽網頁，說不清楚請看以下架構圖

动态端口转发可用于绕过中国的防火墙或任何其他防火墙或互联网过滤系统。 在本教程中，我们将了解如何使用两个 SSH 客户端（OpenSSH 和 PuTTY）来创建具有动态端口转发功能的安全 SSH 隧道。 要求 您的计算机和远程服务器之间将建立 SSH 隧道。

Alternatively, select ‘Dynamic’ if you want PuTTY to provide a local SOCKS 4/4A/5 proxy on a local port (note that this proxy only supports TCP connections; the SSH protocol does not support forwarding UDP).

Tunneling 指的是將網路上的 A、B 兩個端點用某種方式連接起來，形成一個「隧道」，讓兩端的通訊能夠穿透某些限制（例如防火牆），或是能將通訊內容加密避免洩漏。

This tutorial helped you to setup local and remote SSH tunnel via the Putty application on Windows server. Which allows to your access services running on remote system or network via SSH network, where you don’t have directly access via port.

In this procedure, we will use Internet Explorer, Firefox and an RDP connection to demonstrate the use of a tunnel with an SSH connection, as well as configuring the tunnel with several other protocol types.

Let’s open PuTTY and start: Now the tunnel is set up to localhost on the tcp port 1339 that you specified as source port. Now you could setup you progrma to use a SOCKS5 proxy to use the tunnel.
