Force programs that do not specify proxy settings to use a proxy (ie: Steam)

I am looking for a software which can route all outgoing/incoming requests through a proxy server rather than via a direction connection to the internet. I have two pieces of software which I cannot use behind a proxy because they do not support proxies.

I would like to avoid tunneling programs, such as WinCap, because they break the honesty policy of my campus network. Instead, I would simply like non-proxied connections to be redirected through the campus proxy.

Can Fiddler do this? If so, how?

This question was marked as an exact duplicate of an existing question.

Yes, it is a similar question. However, the answer involves SSH tunneling, which, if I were caught using it on this campus, would have severe consequences. – Oliver Spryn Feb 11 '12 at 15:57
If you find it's the same question, but don't like the answers try adding a bounty or alike to the original question to garner better/different answers. – Ƭᴇcʜιᴇ007 Feb 11 '12 at 16:00
What application-layer protocols and ports are those two applications using? HTTP,80 or something else? – RedGrittyBrick Feb 11 '12 at 16:16
@spryno724: You have interpreted that answer wrong, it says combined with a SSH tunnel and it does not say using a SSH tunnel. – Tom Wijsman Feb 11 '12 at 20:45
My tun2socks software seems to be exactly what you need. It makes a virtual network interface that forwards all incoming connections through SOCKS. – Ambroz Bizjak Feb 18 '12 at 21:50

It sounds like you (or more specifically, the campus) need a transparent proxy

Proxycap can do this although that it is paid, an alternative free version could be Proxfier. These are proxy clients that connect applications to proxies, which is what you described. It does not do any tunneling on top of that...

They simple let you specify what applications you want to connect with which proxies.

Can Fiddler do this? If so, how?

Fiddler is mainly intended to be a HTTP(S) protocol debugger, while you can script things it would be kind of a work-around to need to run Fiddler (which it's overhead) as a proxy client.

Hmm... is this still tunneling? – Oliver Spryn Feb 11 '12 at 19:20
