6.11.1

LANs, WANs and the Device

The actual physical connection determines whether the Device ports are LAN or WAN ports. There

are two separate IP networks, one inside the LAN network and the other outside the WAN network

as shown next.

DHCP Setup

DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to

obtain TCP/IP configuration at start-up from a server. You can configure the Device as a DHCP

server or disable it. When configured as a server, the Device provides the TCP/IP configuration for

the clients. If you turn DHCP service off, you must have another DHCP server on your LAN, or else

the computer must be manually configured.

IP Pool Setup

The Device is pre-configured with a pool of IP addresses for the DHCP clients (DHCP Pool).

Do not

assign static IP addresses from the DHCP pool to your LAN computers.

6.11.3

DNS Server Addresses

DNS (Domain Name System) maps a domain name to its corresponding IP address and vice versa.

The DNS server is extremely important because without it, you must know the IP address of a

computer before you can access it. The DNS server addresses you enter when you set up DHCP are

passed to the client machines along with the assigned IP address and subnet mask.

There are two ways that an ISP disseminates the DNS server addresses.

•

The ISP tells you the DNS server addresses, usually in the form of an information sheet, when

you sign up. If your ISP gives you DNS server addresses, enter them in the

DNS Server

fields in

the

DHCP Setup

screen.

•

Some ISPs choose to disseminate the DNS server addresses using the DNS server extensions of

IPCP (IP Control Protocol) after the connection is up. If your ISP did not give you explicit DNS

servers, chances are the DNS servers are conveyed through IPCP negotiation. The Device

supports the IPCP DNS server extensions through the DNS proxy feature.

Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It

does not mean you can leave the DNS servers out of the DHCP setup under all circumstances. If

your ISP gives you explicit DNS servers, make sure that you enter their IP addresses in the

DHCP Setup

screen.

6.11.4

LAN TCP/IP

The Device has built-in DHCP server capability that assigns IP addresses and DNS servers to

systems that support DHCP client capability.

IP Address and Subnet Mask

Similar to the way houses on a street share a common street name, so too do computers on a LAN

share one common network number.

Where you obtain your network number depends on your particular situation. If the ISP or your

network administrator assigns you a block of registered IP addresses, follow their instructions in

selecting the IP addresses and the subnet mask.

If the ISP did not explicitly give you an IP network number, then most likely you have a single user

account and the ISP will assign you a dynamic IP address when the connection is established. If this

is the case, it is recommended that you select a network number from 192.168.0.0 to

192.168.255.0 and you must enable the Network Address Translation (NAT) feature of the Device.

The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for

private use; please do not use any other number unless you are told otherwise. Let's say you select

192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to

192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the

network number while the last number identifies an individual computer on that network.

Once you have decided on the network number, pick an IP address that is easy to remember, for

instance, 192.168.1.254, for your Device, but make sure that no other device on your network is

using that IP address.

The subnet mask specifies the network number portion of an IP address. Your Device will compute

the subnet mask automatically based on the IP address that you entered. You don't need to change

the subnet mask computed by the Device unless you are instructed to do otherwise.

Private IP Addresses

Every machine on the Internet must have a unique address. If your networks are isolated from the

Internet, for example, 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:

• 10.0.0.0

— 10.255.255.255

• 172.16.0.0

— 172.31.255.255

•

192.168.0.0 — 192.168.255.255
