By running a server (of course on Linux or BSD), I hope to accomplishing the following by HTTP tunneling. I didn't know of any better forum to post this to so...

scenario: Users from inside a censored network (of about 300 windows 2k clients) connect to the web only via IE since it contains unchangeable proxy settings to a local server (which all traffic goes through for some reason). The only usable port is 80.

solution: setup an external server in order to tunnel HTTP traffic. Users would only use their browsers (IE) to connect to the tunnel mechanism (and login or something).

Beef: What is the simplest and easiest way to accomplish this? I could setup putty to tunnel HTTP with ssh, but this probably won't work since IE only connects through a local proxy server (that is specified in IE's proxy settings which users aren't allowed to change.

Thanks for your help and input.

get putty working, and portforward a local port, e.g. 1234, to a proxy reachable via your server. you can just use something simple like tinyproxy on the machine itself if you want. then just point your browser to use 127.0.0.1:1234 as it's proxy and the job's a good 'un/

I'm not sure if we understand eachother. So on the internal censored box, one would go to 127.0.0.1ort in the browser to reach my server (which is not within the network)?

if you are port forwarding via putty, yes.

How about an in browser HTTP tunnel (like www.anonymouse.org). That seems like it would be much easier to use. All of the ones popular enough to be of decent speed are blocked, so I'd like to make my own.

what's not easy?? an anonymous proxy is not a tunnel in any way whatsoever, but sure.. run your own if you want to.
