DESCRIPTION
Use the web configurator to easily configure the rich range of features on
the ZyWALL.
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.
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 earlier configuration.
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.
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.
Use this feature to have the ZyWALL assign IP addresses, an IP default
gateway and DNS servers to computers on your network.
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 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 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.
The ZyWALL can function as a transparent firewall. The ZyWALL
bridges traffic traveling between the ZyWALL's interfaces and still filters
and inspects packets. You do not need to change the configuration of
your existing network.
(R)STP detects and breaks network loops and provides backup links
between switches, bridges or routers. It allows a switch to interact with
other (R)STP -compliant switches in your network to ensure that only
one path exists between any two stations on the network.
Zero configuration mode provides Internet and VPN access for mobile
users or telecommuters with little or no configuration. The ZyWALL auto-
detects and automatically configures many settings. It also provides
extra protection against unauthorized access.
You can specify which computers can access the ZyWALL based on
their MAC addresses.
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.
Use packet tracing and logs for troubleshooting. You can send logs from
the ZyWALL to an external syslog server.
PPPoE mimics a dial-up Internet access connection.
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.
A UPnP-enabled device can dynamically join a network, obtain an IP
address and convey its capabilities to other devices on the network.
The ZyWALL supports Time Warner's RoadRunner Service in addition
to standard cable modem services.
