Device Management
Use the web configurator to easily configure the rich range of features on
the ZyWALL.
Firmware Upgrade
Download new firmware (when available) from the ZyXEL web site and
use the web configurator, an FTP or a TFTP tool to put it on the
ZyWALL.
Note: Only upload firmware for your specific model!
Configuration Backup &
Restoration
Make a copy of the ZyWALL’s configuration. You can put it back on the
ZyWALL later if you decide to revert back to an earl
i
er configuration.
Network Address
Translation (NAT)
Each computer on your network must have its own unique IP address.
Use NAT to convert your public IP address(es) to multiple private IP
addresses for
the computers on your network.
Port Forwarding
If you have a server (mail or web server for example) on your network,
you can use this feature to let people access it from the Internet.
DHCP (Dynamic Host
Configuration Protocol)
Use this feature to have the ZyWALL assign IP addresses, an IP default
gateway and DNS servers to computers on your network.
Dynamic DNS Support
With Dynamic DNS (Domain Name System) support, you can use a
fixed URL, www.zyxel.com for example, with a dynamic IP address. You
must register for this service with a Dynamic DNS service provider.
IP Multicast
IP multicast is used to send traffic to a specific group of computers. The
ZyWALL supports versions 1 and 2 of IGMP (Internet Group
Management Protocol) used to join multicast groups (see RFC 2236).
IP Alias
IP alias allows you to subdivide a physical network into logical networks
over the same Ethernet interface with the ZyWALL itself as the gateway
for each subnet.
Time and Date
Get the current time and date from an external server when you turn on
your ZyWALL. You can also set the time manually. These dates and
times are then used in logs.
Logging and Tracing
Use packet tracing and logs for troubleshooting. You can send logs from
the ZyWALL to an external syslog server.
PPPoE
PPPoE mimics a dial-up Internet access connection.
PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) enables secure transfer of
data through a Virtual Private Network (VPN). The ZyWALL supports
one PPTP connection at a time.
Universal Plug and Play
(UPnP)
A UPnP-enabled device can dynamically join a network, obtain an IP
address and convey its capabilities to other devices on the network.
RoadRunner Support
The ZyWALL supports Time Warner’s RoadRunner Service in addition to
standard cable modem services.
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.
