Note: We are using Windows 7 for this guide, but the steps should be similar for other versions of Windows.
Follow these instructions to configure the Safari browser to use a Proxy Server on Windows:
Click on the "cog" menu at the top of the screen.
Click on the "Preferences..." menu item.
Click on the "Advanced" tab of the menu bar.
Under "Proxies:", click on the "Change Settings..." button.
In the LAN Settings, uncheck the box that says "Automatically detect settings". Then in the Proxy Server Section, click the checkbox to enable "Use a proxy server for your LAN..."
Now when you surf the web, you will be surfing by using the Proxy Server. The first time you surf, depending on your account's authentication settings, you may be asked to enter your credentials, which were supplied in your Welcome Email.
To stop using the Proxy Server, repeat the above steps, but uncheck the box that says "Web Proxy (HTTP)" in the "Change Settings..." section.
