Port Forwarding
WebVPN supports TCP-based port forwarding through a Java-based applet located on the
portal home page. The Java-based applet maps an application-specific port on the end user’s
computer to the same port on a server located behind the ASA Security Appliance. An
example of this would be mapping port 22 for SSH access from the end user’s computer to a
UNIX server inside the enterprise network.
A list of applications preconfigured for port forwarding can be found through the Start TCP
application access link on the Portal home page. Once clicked, a new window, shown in
Figure 13-9, is opened with a list of applications. All of these listed applications are available
until the window is closed.
