So you have build an ssh tunnel http://www.r00t.gr/how-to-easily-create-a-ssh-tunnel-using-windows-in-startup-boot/ and you want to redict all you traffic through it. You can configure all browsers and email clients and utorent to use the proxy, or you can download proxifier http://www.proxifier.com/download.htm and set it up to use one proxy. It’s really cheap, 40$ for a lifetime licence.
Cool tools like that, I don’t mind paying for!
I use that trick on my personal computers to encrypt all my traffic through one of my dedicated servers
