I will tell you something: why don’t make a Windows software (GNU Freeware) that does exactly this function. You Linux geeks are genius, but helping people it’s more than type some kind of linux “command”. There are Windows people that need this too. We Windows users need help too. Yeah, I’m newbie, Linux may be great, but there are too many complex “command line” instructions to me (I know the graphical interface is as easy as Windows), but get complex things working in Linux is a pain. In Windows someone program an application, and it’s done. I know I may sound lazy, but not everyone is a genius. This is only an example. There are a lot of functions in Windows that need an application to get it work. For example, I was looking for a transparent proxy to VMware o Virtual PC, that works at ethernet level. In linux it may be easy for a genius, but in Windows it’s impossible without an application or a complex configuration. If you know a way to do that in Windows, it will be great!. Thank you…….. :)

Good to know that there are alternative solutions.

The solution I describe seems to be more robust if you want to be sure that all outgoing traffic makes it through the proxy or in case the software cannot be trusted (proprietary).

You can also use $tsocks application_name

It overwrites LD_PRELOAD var to force C’s connect calls to go through your SOCKS proxy.

It’s not that elegant as defining some ipables rules for it, but it’s simpler and allows you to define which application should be using the proxy or not.

There is an example here https://github.com/darkk/redsocks (scroll to the bottom). You can append “–dport 80″ if you want to specify port 80 only.
