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.
Housing
Your ZyXEL Device's compact and ventilated housing minimizes space requirements making it easy
to position anywhere in your busy office.
