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/
Name
Enter 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.

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.
