If you need to have your browser access the internet with another IP and you have SSH access a remote server, you can tunnel your connection through that server.

This means that all traffic will pass through the proxy before reaching the Internet.

This is useful for things like:

  • Accessing your university's proxy so that you can access things like paywalled articles and books.

  • Mask your IP

Set up SSH tunnel to a proxy server

Description: create a SOCKS proxy on localhost:9999 (choose any unused port) over an SSH connection to <remoteserver> on port <portnum>, using username <user>. You may be prompted for your password.


$ ssh -D 9999 -f -C -N <user>@<remoteserver> -p <portnum>

Actual Example:

$ ssh -D 9999 -f -C -N -p 52831

Configure Firefox to use that proxy

  • Open Preferences > Advanced > Network

  • Click Settings:

settings Click Settings, in the Network tab

  • Select Manual proxy configuration and add a SOCKS host (v5):

firefox-connection-settins Add a SOCKS host "localhost" and port 9999 (for a tunnel created as per the previous point)

Example for Firefox v 57+

  • Go to Settings > Preferences:

firefox-v-57-preferences Click the settings button then choose Preferences

  • Scroll down and click on "Settings" under "Network Proxy"
