What Are SSL Tunnel VPN’s ?

This type of SSL VPN allows a user to use a typical Web browser to securely access multiple network services, including applications and protocols that are not web-based, through a tunnel that is running under SSL. SSL tunnel VPNs require that the Web browser be able to handle active content, which allows them to provide functionality that is not accessible to SSL portal VPNs. Examples of active content include Java, JavaScript, Active X, or Flash applications or plug-ins.
