clients to connect to the ZyWALL wirelessly. Enable wireless security
(WEP, WPA(2), WPA(2)-PSK) and/or MAC filtering to protect your
wireless network.
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 earlier 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.
