By using the Barricade's built-in DHCP (Dynamic Host Control
Protocol) server you are allowing the Barricade to handle all the IP
addressing on your Local Area Network (LAN). This can save you
much of the time and hassle of administrating your network. If you
have a server on your network that requires a static IP address,
you may still use the DHCP server and manually assign a static IP
address to your server. We recommend leaving the DHCP Server
"Enabled."
10. In most applications, you should leave the DHCP Server
"Enabled." If you prefer to handle all the IP addressing on your
network yourself, click disable.
11. There is usually no need to change the IP address pool. If you
change the pool range, make sure the rst three octets match the
Barricade's IP address, i.e., 192.168.2.xxx thru 192.168.2.yyy
A Domain Name Server (DNS) is like an index of names and Web
addresses. If you type a Web address into your browser, such as
www.smc-europe.com, a DNS server will nd that name in its index
and nd the matching IP address: 198.137.240.92. Most ISPs provide
a DNS server for speed and convenience. Since you are connecting
to the Internet with dynamic IP settings, it is likely that your DNS
servers are also provided dynamically.
12. Click "ENTER" when nished.
At this point, the LAN side of your Barricade is now congured. But
you must still congure it to connect to the Internet. There are three
different general congurations for high-speed Internet connections.
You need to know about your Internet connection to determine which
conguration to use. You found out most of what you need to know
when you recorded your IP settings in earlier steps. Here are some
guidelines to determine which conguration you should use:
