Chapter 1 Configuring Clientless SSL VPN
Licensing Requirements
Clientless SSL VPN lets users establish a secure, remote-access VPN tunnel to an ASA using a web
browser. Users do not need a software or hardware client.
Clientless SSL VPN provides secure and easy access to a broad range of web resources and both
web-enabled and legacy applications from almost any computer that can reach HTTP Internet sites. They
include:
•
Internal websites
•
Web-enabled applications
•
NT/Active Directory file shares
•
E-mail proxies, including POP3S, IMAP4S, and SMTPS
•
Microsoft Outlook Web Access Exchange Server 2000, 2003, and 2007
•
Microsoft Web App to Exchange Server 2010 in 8.4(2) and later.
•
Application Access (that is, smart tunnel or port forwarding access to other TCP-based applications)
Clientless SSL VPN uses Secure Sockets Layer Protocol and its successor, Transport Layer Security
(SSL/TLS1) to provide the secure connection between remote users and specific, supported internal
resources that you configure at an internal server. The ASA recognizes connections that need to be
proxied, and the HTTP server interacts with the authentication subsystem to authenticate users.
The network administrator provides access to resources by users of clientless SSL VPN sessions on a
group basis. Users have no direct access to resources on the internal network.
