Chapter 1 Getting To Know Your ZyXEL Device 26
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the ZyXEL Device and other UPnP enabled devices can
dynamically join a network, obtain an IP address and convey its capabilities to other devices
on the network.
PPPoE (RFC2516)
PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your
ISP to use their existing network configuration with newer broadband technologies such as
ADSL. The PPPoE driver on the ZyXEL Device is transparent to the computers on the LAN,
which see only Ethernet and are not aware of PPPoE thus saving you from having to manage
PPPoE clients on individual computers. The ZyXEL Device also includes PPPoE idle time-out
(the PPPoE connection terminates after a period of no traffic that you configure) and PPPoE
Dial-on-Demand (the PPPoE connection is brought up only when an Internet access request is
made).
Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address
used within one network (for example a private IP address used in a local network) to a
different IP address known within another network (for example a public IP address used on
the Internet).
Dynamic DNS Support
With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address,
allowing the host to be more easily accessible from various locations on the Internet. You must
register for this service with a Dynamic DNS service provider.
DHCP
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to
obtain the TCP/IP configuration at start-up from a centralized DHCP server. The ZyXEL
Device has built-in DHCP server capability enabled by default. It can assign IP addresses, an
IP default gateway and DNS servers to DHCP clients. The ZyXEL Device can now also act as
a surrogate DHCP server (DHCP Relay) where it relays IP address assignment from the actual
real DHCP server to the clients.
IP Alias
IP Alias allows you to partition a physical network into logical networks over the same
Ethernet interface. The ZyXEL Device supports three logical LAN interfaces via its single
physical Ethernet interface with the ZyXEL Device itself as the gateway for each LAN
network.
