ZyWALL USG 1000 User’s Guide

The ZyWALL automatically loads the ZyWALL SecuExtender client program to your 
computer after a successful login. The ZyWALL SecuExtender lets you:

• Access servers, remote desktops and manage files as if you were on the local 

network. 

• Use applications like e-mail, file transfer, and remote desktop programs directly 

without using a browser. For example, you can use Outlook for e-mail instead of 

the ZyWALL’s web-based e-mail. 

• Use applications, even proprietary applications, for which the ZyWALL does not 

offer SSL application objects. 

The applications must be installed on your computer. For example, to use the VNC 
remote desktop program, you must have the VNC client installed on your 
computer.

The ZyWALL SecuExtender icon color indicates the SSL VPN tunnel’s connection 
status.

• Red: the SSL VPN tunnel is not connected. You cannot connect to the SSL 

application and network resources.

• Green: the SSL VPN tunnel is connected. You can connect to the SSL application 

and network resources.You can also use another application to access resources 

behind the ZyWALL. 

• Gray: the SSL VPN tunnel’s connection is suspended. This means the SSL VPN 

tunnel is connected, but the ZyWALL SecuExtender will not send any traffic 

through it until you right-click the icon and resume the connection.
