3.4  Wizard Setup: Screen 3 
The fifth wizard screen allows you to configure WAN IP address assignment, DNS server 
address assignment and the WAN MAC address. 
3.4.1  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.
3.4.2  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.
Connection ID/
NameEnter the connection ID or connection name in this field. It must follow the c:id 
and n:name format. For example, C:12 or N:My ISP. 
This field is optional and depends on the requirements of your ISP.

192.168.0.0-192.168.255.255
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.

51Chapter 3 Wizard Setup
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. 
Lets 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 Prestige, 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 Prestige will 
compute the subnet mask automatically based on the IP address that you entered. You dont 
need to change the subnet mask computed by the Prestige unless you are instructed to do 
otherwise.
3.4.3  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 Prestige can get the DNS server addresses in the following ways.
1The 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 DHCP Setup.
2If the ISP did not give you DNS server information, leave the DNS Server fields in 
DHCP Setup set to 0.0.0.0 for the ISP to dynamically assign the DNS server IP addresses.
3.4.4  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. 
						

							Prestige 334 User’s Guide
Chapter 3 Wizard Setup52
You can configure the WAN ports MAC address by either using the factory default or cloning 
the MAC address from a computer on your LAN. 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.
The fifth wizard screen varies according to the type of encapsulation that you select in the 
third wizard screen.

Gateway IP AddressType the IP address of the gateway. The gateway is an immediate 
neighbour of your Prestige that will forward the packet to the destination. 
The gateway must be a router on the same segment as your Prestiges 
LAN or WAN port.
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 Prestige uses a system DNS server (in the order you specify 
here) to resolve domain names for VPN, DDNS and the time server.

Third DNS Server 
Select From ISP if your ISP dynamically assigns DNS server information 
(and the Prestiges WAN IP address). The field to the right displays the 
(read-only) DNS server IP address that the ISP assigns. 
Select User-Defined if you have the IP address of a DNS server. Enter the 
DNS servers IP address in the field to the right. 
Select None if you do not want to configure DNS servers. If you do not 
configure a system DNS server, you must use IP addresses when 
configuring VPN, DDNS and the time server.
WAN MAC AddressThe MAC address field allows you to configure the WAN ports MAC 
Address by either using the factory default or cloning the MAC address 
from a computer on your LAN.
Factory Default Select this option to use the factory assigned default MAC Address.

whose MAC you are cloning. 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.

Table 8   System General Setup
LABELDESCRIPTION
System NameChoose a descriptive name for identification purposes. It is recommended you 
enter your computer’s “Computer name” in this field (see the Wizard Setup 
chapter for how to find your computer’s name). This name can be up to 30 
alphanumeric characters long. Spaces are not allowed, but dashes “-” and 
underscores _ are accepted.
Domain NameEnter the domain name (if you know it) here. If you leave this field blank, the ISP 
may assign a domain name via DHCP. 
The domain name entered by you is given priority over the ISP assigned domain 
name.
Administrator 
Inactivity TimerType how many minutes a management session (either via the web configurator 
or SMT) can be left idle before the session times out. The default is 5 minutes. 
After it times out you have to log in with your password again. Very long idle 
timeouts may have security risks. A value of 0 means a management session 
never times out, no matter how long it has been left idle (not recommended).
System DNS Servers (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 Prestige uses a system DNS server (in the order you specify 
here) to resolve domain names for VPN, DDNS and the time server.
First DNS Server
Second DNS Server
Third DNS Server 
Select From ISP if your ISP dynamically assigns DNS server information (and the 
Prestiges WAN IP address). The field below displays the (read-only) DNS server 
IP address that the ISP assigns. 
Select User-Defined if you have the IP address of a DNS server. Enter the DNS 
servers IP address in the field below. If you chose User-Defined, but leave the IP 
address set to 0.0.0.0, User-Defined changes to None after you click Apply. If 
you set a second choice to User-Defined, and enter the same IP address, the 
second User-Defined changes to None after you click Apply. 
Select None if you do not want to configure DNS servers. If you do not configure 
a system DNS server, you must use IP addresses when configuring VPN, DDNS 
and the time server.

4.3  Dynamic DNS
Dynamic DNS allows you to update your current dynamic IP address with one or many 
dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You 
can also access your FTP server or Web site on your own computer using a domain name (for 
instance myhost.dhs.org, where myhost is a name of your choice) that will never change 
instead of using an IP address that changes each time you reconnect. Your friends or relatives 
will always be able to call you even if they dont know your IP address.
First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is 
for people with a dynamic IP from their ISP or DHCP server that would still like to have a 
domain name. The Dynamic DNS service provider will give you a password or key.
4.3.1  DynDNS Wildcard
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the 
same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, 
for example, www.yourhost.dyndns.org and still reach your hostname.
