i have seen a lot of explanations on setting up a ssh tunnel from work to home and vice versa. i am trying to do something hopefully a bit easier. i have an old macbook pro running 14.04 as a single boot system. i have loaded openssh server on it and i am just trying to use it to browse securely with firefox. do i have to have a machine on either side of the ISP router for this to happen? i work remote. therefore my 'work' office is also behind the ISP router. lots of ssh setup details on the net, just nothing like this. thank you for any advice.
