8.3 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 32 Private IP Address Ranges

10.0.0.0
172.16.0.0
192.168.0.0
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.

DESCRIPTION
Set the priority for the default WAN connection.
Metric represents the "cost" of transmission for routing purposes. IP routing uses
hop count as the measurement of cost, with a minimum of 1 for directly connected
networks. Enter a number that approximates the cost for this link. The number
need not be precise, but it must be between 1 and 15. In practice, 2 or 3 is usually
a good number.
NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that
enable a computer to connect to and communicate with a LAN. For some dial-up
services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls.
Select this check box to forward NetBIOS packets from the LAN to the WAN and
from the WAN to the LAN. If your firewall is enabled with the default policy set to
block WAN to LAN traffic, you also need to enable the default WAN to LAN firewall
rule that forwards NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the LAN to the WAN
and from the WAN to the LAN.
