While connected to a VPN (SwissVPN service), a content filter at a site I'm working at blocked a web page. This was perplexing, since the local site's filter should not be able to see my traffic, right? So I assume my web browsing activity was not going through the VPN tunnel. How can I configure the OS to send ALL traffic though the currently connected VPN tunnel? I'm using OSX Lion and Windows 7. Thanks!
