When you activate SharePlug, it creates a virtual computer that represents your real computer back at home or office behind firewall. You can use this virtual computer to securely access Windows shared folders, Web server or any service running on the real computer that's compatible with TCP port forwarding. You don't need to sign-up for any monthly service or install software on every computer you wish to connect to. You simply need to setup a sharing gateway server on your remote site and run SharePlug.
