This page describes how you can utilize Your Freedom to use STEAM through a restrictive firewall or proxy.

First of all, you need Proxycap (alternatively: WideCap). Download Proxycap from http://proxylabs.netwu.com/ , or WideCap from the WideCap page.

Go to Preferences -> Proxies:

 

 

Set up the following options: socks 5, localhost, 1080.

Moreover, make sure UDP is ticked..

Then add steam.exe and hl.exe (from your steam folder[s]) and it should work

Start your freedom, and open steam via Proxycap (Sockscap).

Good luck :-)
