CHAPTER 6 Network 6.1 Overview This chapter discusses the network configuration screens. The Network screens allow you to configure TCP/IP and PPPoE settings for the NSA. 6.1.1 What You Can Do in the Network Screens • Use the TCP/IP screen (Section 6.2 on page 126) to assign the NSA a dynamic or static IP address and DNS information • Use the PPPoE screen (Section 6.3 on page 129) to configure PPPoE settings for a direct Internet connection. 6.1.2 What You Need to Know About Network 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 performance. Your network equipment such as computers, switches and routers must be capable of supporting jumbo frames.

Network
6.1
Overview
This chapter discusses the network configuration screens. The
Network
screens
allow you to configure TCP/IP and PPPoE settings for the NSA.
6.1.1
What You Can Do in the Network Screens
Use the
TCP/IP
screen (
Section 6.2 on page 126
) to assign the NSA a dynamic
or static IP address and DNS information
Use the
PPPoE
screen (
Section 6.3 on page 129
) to configure PPPoE settings for
a direct Internet connection.
6.1.2
What You Need to Know About Network
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
performance. Your network equipment such as computers, switches and routers
must be capable of supporting jumbo frames. You also need to enable jumbo
frames in all related network devices.
