SSL VPN
A SSL VPN (Secure Sockets Layer virtual private network) allows users to 
establish a secure, remote-access VPN tunnel to this device by using a web 
browser. Users do not need a software or hardware client preinstalled on their 
computers. SSL VPN provides secure, easy access to a broad range of web 
resources and web-enabled applications from almost any computer on the 
Internet. They include:
• Internal websites
• Web-enabled applications
• NT/Active Directory file shares (i.e. My Network Place)
• MS Outlook Web Access
• Application Access (port forwarding access to other TCP-based 
applications)
SSL VPN uses the Secure Sockets Layer protocol and its successor, Transport 
Layer Security, to provide a secure connection between remote users and 
specific, supported internal resources configured at a central site. This device 
recognizes connections that must be proxied, and the SSL VPN web portal 
interacts with the authentication subsystem to authenticate users.
Access to resources by users of SSL VPN sessions is provided on a group basis. 
Users such as business partners can be put into a group that has no direct access 
to resources 
on the internal network. Or, for users that require access to all resources in the 
internal network, this device supports Virtual Passage, which allows authorized 
users to obtain an IP address from this device through a SSL VPN tunnel and are 
then a part of the internal network.
