• If the assignment is static, all computers on the network have
a permanently assigned IP address. There are no computers
that have the same IP address.
Most ISPs make dynamic IP address assignments through DHCP
(Dynamic Host Configuration Protocol). When a computer
connects to the network, a DHCP server at the ISP assigns that
computer an IP address. The manual assignment of IP addresses is
not necessary with this system.
Some ISPs assign the IP addresses through PPPoE (Point-to-Point
Protocol over Ethernet). PPPoE emulates a standard dial-up
connection to provide some of the features of Ethernet and PPP.
This system allows the ISP to use the billing, authentication, and
security systems designed for dial-up, DSL modem and cable
modem service. When the SOHO 6 Wireless is configured to use
PPPoE, a button on the System Status page controls the connection
to the external network.
Your ISP can tell you how their system assigns the IP addresses.
Configure the SOHO 6 Wireless external network
for dynamic addressing
The default configuration sets the SOHO 6 Wireless to get the
external address information through DHCP. If your ISP supports
this method, the SOHO 6 Wireless gets IP address information
from the ISP when the SOHO 6 Wireless reboots and connects to
the Internet. The SOHO 6 Wireless does not require any additional
configuration.
Configure the SOHO 6 Wireless external network
for static addressing
If your ISP assigns static IP address, you must move the IP address
data from your computer to the SOHO 6 Wireless. This
