Appendix A Product Specifications

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 

Configuration Protocol)

Use this feature to have the ZyXEL Device 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 

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 UNIX syslog server.

PPPoE

PPPoE mimics a dial-up over Ethernet Internet access connection.

PPTP Encapsulation

Point-to-Point Tunneling Protocol (PPTP) enables secure transfer of data 

through a Virtual Private Network (VPN). The ZyXEL Device supports 

one PPTP connection at a time.

Universal Plug and Play 

(UPnP)

The ZyXEL Device can communicate with other UPnP enabled devices 

in a network. 

RoadRunner Support

In addition to standard cable modem services, the ZyXEL Device 

supports Time Warner’s RoadRunner Service.
