I'm on a network with no internet access, but I have SSH access to a server that sits on my internal network, and the internet.

I would like certain programs to be able to access the internet, like windows update and my antivirus software etc.

If I install a proxy server on that server I can use the internet from my pc. But I don't want to do that.

Is there a way that I can configure a web browser and perhaps putty to let me "tunnel out?" through the server to the internet.
