8.1 Overview
This chapter discusses the network configuration screens. The Network screens
allow you to configure TCP/IP and PPPoE settings for the NSA.
8.2 What You Can Do
• Use the TCP/IP screen (
) to assign the NSA a dynamic
or static IP address and DNS information
• Use the PPPoE screen (
) to configure PPPoE settings
for a direct Internet connection.
8.3 What You Need to Know
IP Address
The NSA needs an IP address to communicate with other devices on your network.
The NSA can get an IP address automatically if you have a device on your network
that gives them out. Or you can assign the NSA a static (fixed) IP address.
DNS Server Address
A DNS (Domain Name System) server maps domain names (like www.zyxel.com)
to their corresponding numerical IP addresses. This lets you use domain names to
access web sites without having to know their IP addresses. The NSA can receive
the IP address of a DNS server automatically (along with the NSA’s own IP
address). You can also manually enter a DNS server IP address in the NSA.
Jumbo Frames
Jumbo frames are Ethernet frames larger than 1500 bytes. They enable data
transfer with less overhead. The bigger the frame, the better the network
