NBG334W User’s Guide

231

The following list, which is not exhaustive, illustrates the standards supported in the

NBG334W.

Time and Date Get the current time and date from an external server when you turn on

your NBG334W. 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

Configuration Protocol)

Use this feature to have the NBG334W 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

NBG334W 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 NBG334W itself as the

gateway for each subnet.

Logging and Tracing Use packet tracing and logs for troubleshooting. You can send logs from

the NBG334W 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 NBG334W supports

one PPTP connection at a time.

Universal Plug and Play

(UPnP)

The NBG334W can communicate with other UPnP enabled devices in a

network.
