Your IP Address

The following wizard screen allows you to assign a fixed IP address or give the NBG334W an

automatically assigned IP address depending on your ISP.

3.4.5

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.

"

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.

3.4.6

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 NBG334W, 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 NBG334W 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 NBG334W unless you are instructed to do

otherwise.

3.4.7

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 NBG334W 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.

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

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.

3.4.8

WAN IP and DNS Server Address Assignment

The following wizard screen allows you to assign a fixed WAN IP address and DNS server

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 NBG334W 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

Third 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.

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

NBG334W’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 the "rom" file (ZyNOS configuration file). It will not change unless you change the

setting or upload a different "rom" 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.

Connection Wizard: STEP 4: Bandwidth management

Bandwidth management allows you to control the amount of bandwidth going out through the

NBG334W’s WAN, LAN or WLAN port and prioritize the distribution of the bandwidth

according to the traffic type. This helps keep one service from using all of the available

bandwidth and shutting out other users.

automatically. Real-time packets, such as VoIP traffic always get higher

priority.
