3.4 Wizard Setup: Screen 3
The third 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.
Table 3-4 Private IP Address Ranges
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
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.
