Use SSH tunnel as a secure forward proxy

A forward proxy proxies in behalf of clients. The following setup will allow you to sit in office and SSH connect to a remote server. The remote server will act as the proxy server to forward all your requests to the destination server.

Use SSH tunnel as a secure forward proxy:

# ssh -D 8080 USER@HOST_NAME.COM

or

# ssh -N -f -D 8080 USER@HOST_NAME.COM

You will need to configure a SOCKS proxy server in Google Chrome by adding these two flags when launch Chrome:

--proxy-server="socks5://127.0.0.1:8080"
--host-resolver-rules="MAP * 0.0.0.0 , EXCLUDE 127.0.0.1"

To set up the forward proxy through Putty:

Open Putty > Connection > SSH > Tunnels:

Source Port: 8080

Destination: (leave blank)

Check "Dynamic"

Click on "Add" button
