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.
