Chapter 6 WAN
P-2302HWUDL-P1 Series User’s Guide

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.
6.1.3 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.
The MAC address screen allows users to configure the WAN port's MAC address by either
using the factory default or cloning your computer’s MAC address. Choose Factory Default
to select the factory assigned default MAC Address.
Otherwise, click Spoof this computer's MAC address - IP Address and enter the IP address
of your computer. 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 recommended that you clone the MAC address prior to hooking up
the WAN Port.
6.1.4 RIP Setup
See Section 7.1.5 on page 107.
6.1.5 DNS Server Address Assignment
The Domain Name entry is what is propagated to the DHCP clients on the LAN. If you leave
this blank, the domain name obtained by DHCP from the ISP is used. While you must enter
the host name (System Name) on each individual computer, the domain name can be assigned
from the ZyXEL Device via DHCP.
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 ZyXEL Device 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 SYSTEM General screen.
