2.4.5

WAN IP Address Assignment

Every computer on the Internet must have a unique IP address. If your networks

are isolated from the Internet, for instance, only between your two branch offices,

you can assign any IP addresses to the hosts without problems. However, the

Internet Assigned Numbers Authority (IANA) has reserved the following three

blocks of IP addresses specifically for private networks.

You can obtain your IP address from the IANA, from an ISP or have it assigned by

a private network. If you belong to a small organization and your Internet access

is through an ISP, the ISP can provide you with the Internet addresses for your

local networks. On the other hand, if you are part of a much larger organization,

you should consult your network administrator for the appropriate IP addresses.

Note: Regardless of your particular situation, do not create an arbitrary IP address;

always follow the guidelines above. For more information on address

assignment, please refer to RFC 1597, Address Allocation for Private Internets

and RFC 1466, Guidelines for Management of IP Address Space.

2.4.6

IP Address and Subnet Mask

Similar to the way houses on a street share a common street name, so too do

computers on a LAN share one common network number.

Where you obtain your network number depends on your particular situation. If

the ISP or your network administrator assigns you a block of registered IP

addresses, follow their instructions in selecting the IP addresses and the subnet

mask.

If the ISP did not explicitly give you an IP network number, then most likely you

have a single user account and the ISP will assign you a dynamic IP address when

the connection is established. The Internet Assigned Number Authority (IANA)

reserved this block of addresses specifically for private use; please do not use any

other number unless you are told otherwise. Let's say you select 192.168.1.0 as

the network number; which covers 254 individual addresses, from 192.168.1.1 to

192.168.1.254 (zero and 255 are reserved). In other words, the first three

numbers specify the network number while the last number identifies an individual

computer on that network.

Once you have decided on the network number, pick an IP address that is easy to

remember, for instance, 192.168.1.1, for your NBG4604, but make sure that no

other device on your network is using that IP address.

The subnet mask specifies the network number portion of an IP address. Your

NBG4604 will compute the subnet mask automatically based on the IP address

that you entered. You don't need to change the subnet mask computed by the

NBG4604 unless you are instructed to do otherwise.

2.4.7

DNS Server Address Assignment

Use DNS (Domain Name System) to map a domain name to its corresponding IP

address and vice versa, for instance, the IP address of www.zyxel.com is

204.217.0.2. The DNS server is extremely important because without it, you must

know the IP address of a computer before you can access it.

The NBG4604 can get the DNS server addresses in the following ways.

1

The ISP tells you the DNS server addresses, usually in the form of an information

sheet, when you sign up. If your ISP gives you DNS server addresses, enter them

in the

DNS Server

fields in the

Wizard

and/or

WAN

> Internet Connection

screen.

2

If the ISP did not give you DNS server information, leave the

DNS Server

fields

set to

0.0.0.0

in the

Wizard

screen and/or set to

From ISP

in the

WAN

>

Internet Connection

screen for the ISP to dynamically assign the DNS server IP

addresses.

Gateway IP Address

Enter the gateway IP address in this field.

System DNS Server Address Assignment (if applicable)

DNS (Domain Name System) is for mapping a domain name to its corresponding IP

address and vice versa. The DNS server is extremely important because without it, you

must know the IP address of a computer before you can access it. The NBG4604 uses a

system DNS server (in the order you specify here) to resolve domain names for DDNS and

the time server.

First DNS Server

Second DNS Server

Enter the DNS server's IP address in the fields provided.

If you do not configure a system DNS server, you must use IP

addresses when configuring DDNS and the time server.

2.4.9

WAN MAC Address

Every Ethernet device has a unique MAC (Media Access Control) address. The MAC

address is assigned at the factory and consists of six pairs of hexadecimal

characters, for example, 00:A0:C5:00:00:02.

This screen allows users to configure the WAN port's MAC address by either using

the NBG4604’s MAC address, copying the MAC address from a computer on your

LAN or manually entering a MAC address. Once it is successfully configured, the

address will be copied to configuration file. It is advisable to clone the MAC

address from a computer on your LAN even if your ISP does not presently require

MAC address authentication.
