content: To use Tunnelblick you need access to a VPN server: your computer is one end of the tunnel and the VPN server is the other end. For more information, see Getting VPN Service.  So if you still need a VPN service what are the benefits of using something like this over the client? I use it because I don't know any better alternative and it works. I'd love to see a thread on alternative open source solutions here, btw. Edit: I actually use OpenVPN on my phone
