Given a network where a webserver is behind a firewall but you have ssh access to a jumpbox, this command will tunnel traffic over ssh on the jumpbox.

-L will tunnel traffic from the local machine port 8080 to protected-web-server.com port 80. Add -N to only forward the ports and not send the terminal in to an ssh session on the jumpbox.

ssh jumpbox-user@jumpbox.com -L 8080:protected-web-server.com:80

Even better, setup the jumpbox to be a SOCKS proxy
