The fourth wizard screen allows you to confi gure WAN IP address
assignment, DNS server address assignment and the WAN MAC
address.
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 offi ces, 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 specifi cally for private networks.

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 organiza-
tion 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.
