ZyXEL Communications 4.6 ユーザーズマニュアル

Media Server User’s Guide

This chapter discusses the network configuration screens. The Network screens allow you to 
configure TCP/IP and PPPoE settings for the NSA.

• Use  the  TCP/IP screen (

) to assign the NSA a dynamic or static IP 

address and DNS information.

• Use UPnP port mapping (

) to automatically configure your Internet 

gateway’s firewall and Network Address Translation (NAT) to allow access to the NSA from the 
Internet.  

• Use  the  PPPoE screen (

) to configure PPPoE settings for a direct Internet 

connection.

• Use  the  Telnet screen (

) to enable or disable Telnet access.

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.

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.

Point-to-Point Protocol over Ethernet (PPPoE) allows the NSA to establish a direct Internet 
connection if you do not have a router. PPPoE is a dial-up connection. You need a username and 
password from your Internet Service Provider (ISP) to set up the connection.
