Chapter 1 Getting To Know Your ZyXEL Device

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 (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 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.

Traditionally, routing is based on the destination address only and the router takes the 
shortest path to forward a packet. IP Policy Routing (IPPR) provides a mechanism to 
override the default routing behavior and alter the packet forwarding based on the policy 
defined by the network administrator. 

The ZyXEL Device's packet filtering functions allows added network security and 
management.

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

TR-069 is a protocol that defines how your ZyXEL Device can be managed via a management 
server such as ZyXEL’s Vantage CNM Access. The management server can securely manage 
and update configuration changes in ZyXEL Devices.
