Firewall You can configure firewall on the ZyXEL Device for secure Internet
access. When the firewall is on, by default, all incoming traffic from the
Internet to your network is blocked unless it is initiated from your
network. This means that probes from the outside to your network are
not allowed, but you can safely browse the Internet and download files
for example.
Content Filter The ZyWALL blocks or allows access to web sites that you specify and
blocks access to web sites with URLs that contain keywords that you
specify. You can define time periods and days during which content
filtering is enabled. You can also include or exclude particular computers
on your network from content filtering.
You can also subscribe to category-based content filtering that allows
your ZyWALL to check web sites against an external database.
IPSec VPN This allows you to establish a secure Virtual Private Network (VPN)
tunnel to connect with business partners and branch offices using data
encryption and the Internet without the expense of leased site-to-site
lines. The ZyWALL VPN is based on the IPSec standard and is fully
interoperable with other IPSec-based VPN products.
Bandwidth Management You can efficiently manage traffic on your network by reserving
bandwidth and giving priority to certain types of traffic and/or to particular
computers.
Remote Management This allows you to decide whether a service (HTTP or FTP traffic for
example) from a computer on a network (LAN or WAN for example) can
access the ZyWALL.
