session terminates.
Broad Application Support for SSL VPN
The Cisco WebVPN Services Module offers extensive application support through its dynamically
downloaded SSL VPN client, enabling network-layer connectivity to virtually any application. The
module’s truly clientless support for Web-based applications allows a low-overhead extension of
network resources to VPN users through a standard Web browser. Pure clientless and thin-client
port forwarding options may be deployed for environments with limited application access
requirements, such as extranets.
Flexibility
IPsec and SSL are complementary technologies that address unique user access requirements;
both may be necessary in order for a company to meet the needs of a diverse user base. Support
for both IPsec and SSL VPN allows businesses to choose the most appropriate technology for
users accessing the network through different scenarios. This provides maximum flexibility and
application access all on one platform, alleviating the need to deploy and manage separate
infrastructures.
Ease of Deployment
The Cisco WebVPN Services Module comes with integrated device manager support. This helps
configure and provision the module without the need for an external element management system,
providing a ready-to-deploy solution.
Modes of Operation
Clientless Mode
The following applications are supported in clientless mode (they all rely on the Web browser as
the client):
●
Web browsing (HTTP/HTTPS)
●
File sharing (Common Internet File System [CIFS])
●
Web e-mail such as Microsoft Outlook Web Access (HTTP/HTTPS) with WebDAV extensions
Thin-Client Mode
The applications supported in the thin-client mode (TCP Port Forwarding, for example) support
TCP/IP client server applications such as mail-based applications (SMTP, POP3, and IMAP4, for
example), terminal services, instant messaging, and Telnet.
Tunnel Mode
Tunnel mode redirects a user’s VPN traffic at the network layer through an SSL tunnel, providing
support for most IP-based applications. While other SSL VPN operation modes offer a limited set
of application support, the tunnel mode supports almost all of the popular corporate applications,
including Meeting-Maker, Microsoft Outlook, Microsoft Exchange, Lotus Notes E-Mail, and Telnet.
Even some legacy applications, such as 3270 terminal emulation, can be supported.
