Home Page
The administrator designs this page to meet the
individual requirements of the end user
. Using this
interface, the end user can conveniently and securely access the internal
network of the organization from any computer that has an Internet connection.
The end user can check e-mail, view or transfer files, visit internal corporate
websites, or run internal web applications from any Web browser. The user
navigates using the buttons provided within the WebVPN interface window. The
following buttons are available:
-
Help – The user can click this icon to access this help system.
-
Show Toolbar – The user can click this icon to show the WebVPN
Toolbar
-
Home – The user can click this icon to return to the home page.
-
Logout – The user can click this icon to end the remote access
session.
Website Access and Browsing Files
If the administrator sets
up end user accounts to access particular websites or file shares, one or more
links appear under Websites on the home page of the end user
. To
access the website or file share, the end user simply clicks the link. If the
site is protected, the end user will have to enter a username and password.
If the administrator has granted end user access to a server that is not
specifically listed, the end user can enter the web address of the server
directly in the Enter Web Address (URL) text box or the Enter Network Path text
box. Alternately, the end user can browse the network by clicking the Browse
Network link.
Once connected to a file share the end user can upload and
download files, creates new folders, delete and rename files by clicking the
appropriate links.
Whenever the end user is visiting a website via a
secure remote access session, a toolbar appears on the webpage. The toolbar is
to remind the end user the access is being provided through the corporate
network.
Port Forwarding
The administrator can configure
certain client/server applications for use by the end user. Starting
Application Access, or Port Forwarding, opens a secure connection between the
end user computer and the remote server. When the window is open or minimized,
the connection is active. If the end user quits the window, the connection
closes.
 |
NOTE:
Port Forwarding requires Sun Microsystems Java Runtime Environment
version 1.4 or later to be installed on the end user system. It can be
downloaded automatically if needed.
|
The chart in the Application Access window lists the available
applications and key details about the secure connection
. This chart is
display only. The end user cannot edit it, and clicking on a cell does not
start the application.
WebVPN provides access to TCP-based applications by mapping
application-specific ports on the PC of the end user to application specific
ports on servers behind the Adaptive Security Appliance. When an end user
accesses an application over WebVPN using hostnames to identify the application
server, the ASA modifies the Windows Hosts file to include a mapping entry for
that application.
The chart has the following fields:
-
Name – The name of an available client application.
-
Local – The hostname, or IP address, and TCP port to configure on
the client application to allow communication with the remote server.
-
Remote – The hostname, or IP address, and TCP port of the remote
server.
-
Bytes In/Out – The amount of data that this application receives or
sends through the secure connection.
-
Sockets –The number of TCP connections that the application is
using.
 |
NOTE:
When using Microsoft Windows, the end user must close the Port
Forwarding window when they finish using a client/server application. If they
shut down the computer without closing this window, the end user might later
have problems running these applications. The end user also might be unable to
access the host of the application, such as a mail server.
