Network Example
25.1.1
What You Need to Know
The ZyWALL can use SSL VPN to provide secure connections to network resources
such as applications, files, intranet sites or e-mail through a web-based interface
and using Microsoft Outlook Web Access (OWA).
Network Resource Access Methods
As a remote user, you can access resources on the local network using one of the
following methods.
Using a supported web browser
Once you have successfully logged in through the ZyWALL, you can access
intranet sites, web-based applications, or web-based e-mails using one of the
supported web browsers.
Using the ZyWALL SecuExtender client
Once you have successfully logged into the ZyWALL, the ZyWALL automatically
loads the ZyWALL SecuExtender client program to your computer. With the
ZyWALL SecuExtender, you can access network resources, remote desktops and
manage files as if you were on the local network. See
Chapter 27 on page 433
for more on the ZyWALL SecuExtender.
