FEATURE | DESCRIPTION |
|
|
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. You can put it back on |
Restoration | the ZyXEL Device later if you decide 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 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 | 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. |
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. |
Logging and Tracing | Use packet tracing and logs for troubleshooting. You can send logs from |
| the ZyXEL Device to an external syslog server. |
PPPoE | PPPoE mimics a |
|
|
PPTP Encapsulation | |
| through a Virtual Private Network (VPN). The ZyXEL Device supports |
| one PPTP connection at a time. |
Universal Plug and Play | A |
(UPnP) | address and convey its capabilities to other devices on the network. |
| Activate UPnP to have the ZyXEL Device communicate with other UPnP- |
| enabled devices in a network. |
RoadRunner Support | The ZyXEL Device 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 ZyXEL Device 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. |
