Appendix A Product Specifications
Table 92 Firmware Features
FEATURE | DESCRIPTION |
Wireless Functionality | Allows IEEE 802.11b and/or IEEE 802.11g wireless clients to connect to |
| the ZyXEL Device wirelessly. IEEE 802.11g clients can connect using |
| the super G function. Enable wireless security (WEP, WPA(2), WPA(2)- |
| PSK) and/or MAC filtering to protect your wireless network. |
| Note: The ZyXEL Device may be prone to RF (Radio |
| Frequency) interference from other 2.4 GHz devices |
| such as microwave ovens, wireless phones, |
| Bluetooth enabled devices, and other wireless LANs. |
|
|
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 ZyXEL |
| Device. |
| Note: Only upload firmware for your specific model! |
|
|
Configuration Backup & | Make a copy of the ZyXEL Device’s configuration and put it back on the |
Restoration | ZyXEL Device later if you decide you want to revert back to an earlier |
| configuration. |
|
|
Network Address | Each computer on your network must have its own unique IP address. |
Translation (NAT) | Use NAT to convert a single public IP address to multiple private IP |
| addresses for the computers on your network. |
|
|
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 ZyXEL Device 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 |
| your ZyXEL Device to check web sites against an external database. |
|
|
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. |
|
|
Time and Date | 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. |
|
|
Port Forwarding | If you have a server (mail or web server for example) on your network, |
| then use this feature to let people access it from the Internet. |
|
|
DHCP (Dynamic Host | Use this feature to have the ZyXEL Device assign IP addresses, an IP |
Configuration Protocol) | 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 |
| ZyXEL Device 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 ZyXEL Device itself as the |
| gateway for each subnet. |
