Non-stop Internet Access with
Multiple WAN and 3G Backups
The ZyWALL USG not only supports
multiple WAN ports but also 3G through
USB or PCMCIA cards. This feature enables
“active-active” load sharing or “active-
passive” failover configuration to deliver
highly reliable network connectivity.
Application Firewall
More and more network applications bring
malicious software into your office. This kind
of unwanted software, especially IM/P2P
applications, may cause bandwidth waste or
even system damage. Using the application
patrol and bandwidth management features,
you can have full control over traffic blocking
or rate limit settings.
Web Security (Secure Web Access):
ZyXEL Safe Browsing
There are increasing network threats coming
from internal sources, since your employees
could surf unknown Web sites located
anywhere. Some Web sites contain malicious
software like Trojan horses, spywares or
worms that could take tolls to your company;
thus finding ways to keep internal users from
surfing dangerous Web sites is becoming an
important issue. ZyXEL Safe Browsing feature
can pinpoint the Web sites with malicious
software and warn the users to stay away
from potential threats.
Device HA: Master Fails and Backup Takes Over
High Availability
High availability is essential in enterprise
networks. It ensures a system or component
can be continuously operational for a desirably
long length of time.
The ZyWALL USG series provide high
availability feature as:
• Multiple WAN ports and configure load
balancing between these ports.
• An auxiliary (backup) Internet connection as
known as out of band Management .
• A backup ZyWALL in the event the master
ZyWALL fails (device HA).
