Chapter 31 Product Specifications
Download new firmware (when available) from the Zyxel web site and use the
web configurator to put it on the Zyxel Device.
Note: Only upload firmware for your specific model!
Make a copy of the Zyxel Device's configuration. You can put it back on the
Zyxel Device 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 Zyxel Device assign IP addresses, an IP default
gateway and DNS servers to computers on your network. Your device can
also act as a surrogate DHCP server (DHCP Relay) where it relays IP address
assignment from the actual real DHCP server to the clients.
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 Zyxel
Device supports versions 1 and 2 of IGMP (Internet Group Management
Protocol) used to join multicast groups (see RFC 2236).
Get the current time and date from an external server when you turn on your
Zyxel Device. You can also set the time manually. These dates and times are
then used in logs.
Use logs for troubleshooting. You can send logs from the Zyxel Device to an
external syslog server.
A UPnP-enabled device can dynamically join a network, obtain an IP address
and convey its capabilities to other devices on the network.
Your device has a stateful inspection firewall with DoS (Denial of Service)
protection. By default, when the firewall is activated, all incoming traffic from
the WAN to the LAN is blocked unless it is initiated from the LAN. The firewall
supports TCP/UDP inspection, DoS detection and prevention, real time alerts,
reports and logs.
URL filtering allows you to block access to Internet web sites of certain URL that
you specify.
You can efficiently manage traffic on your network by reserving bandwidth
and giving priority to certain types of traffic and/or to particular computers.
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
Zyxel Device.
It allows your ISP to use their existing network configuration with newer
broadband technologies such as ADSL. The PPPoE driver on your device is
transparent to the computers on the LAN, which see only Ethernet and are not
aware of PPPoE thus saving you from having to manage PPPoE clients on
individual computers.
PPPoE idle time out
PPPoE dial on demand
Your device supports up to 8 Permanent Virtual Circuits (PVCs).
Your device's packet filtering function allows added network security and
management.
