Chapter 1 Getting To Know Your ZyXEL Device

ZyXEL’s Media Bandwidth Management allows you to specify bandwidth classes based on an 
application and/or subnet. You can allocate specific amounts of bandwidth capacity 
(bandwidth budgets) to different bandwidth classes. 

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.

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.

A combination of switch and router makes your ZyXEL Device a cost-effective and viable 
network solution. You can connect up to four computers to the ZyXEL Device without the 
cost of a hub. Use a hub to add more than four computers to your LAN.

The ZyXEL Device supports the IEEE 802.11g standard, which is fully compatible with the 
IEEE 802.11b standard, meaning that you can have both IEEE 802.11b and IEEE 802.11g 
wireless clients in the same wireless network.
