DSL-G604T 54Mbps Wireless ADSL2/2+ Modem/Router Manual

LAN Configuration

LAN is short for Local Area Network. This is considered your internal network. These are the IP

settings of the LAN interface for the DSL-G604T and may be referred to as Private settings. You may

change the LAN IP address if needed. The LAN IP address is private to your internal network and

cannot be seen on the Internet.

IP Address:

The IP address of the LAN interface. The default IP address is 10.1.1.1.

Subnet Mask:

The subnet mask of the LAN interface. The default subnet mask is 255.0.0.0.

DHCP

Dynamic Host Configuration Protocol (DHCP) allows the gateway to automatically obtain the IP

address from a DHCP server on the service provider’s network. The service provider assigns a global

IP address from a pool of addresses available to the service provider. Typically the IP address assigned

has a long lease time, so it will likely be the same address each time the Router requests an IP address.

If DHCP is not enabled on the Router, it is necessary for the user to assign a static IP address at each

computer on your LAN.

To setup DHCP for your LAN, first enable the Router as a DHCP server by clicking the corresponding

DHCP Server

radio button in the window above and enter the

Starting IP Address

and

Ending IP

address

to create a pool of IP addresses to be assigned to other end nodes (computers, routers, etc.) on

the LAN. The

Lease Time

field is the time the Server will set for devices using DHCP to re-request an

IP Address. When using the Router in DHCP mode you may also configure

DNS

settings for the

LAN. Click the

DNS Mode

radio button to auto to allow the Router to automatically relay DNS

settings to properly configured DHCP clients. Click Manual to manually enter the Primary and

Secondary DNS IP addresses. When the Router has been enabled as DHCP Server the administrator of

the server can assign a

Static IP

address to each computer on the LAN from the workstation where the

DCHP server has been enabled. To assign a Static IP address to a computer on the LAN, enter the IP

and MAC address in the Static IP Assignment field. Click

Apply

to implement information set in this

table.

DNS

DNS or Domain Name Server is a system that translates Domain Names into IP addresses. Setting up

a DNS will allow the router to contact the DNS to ask it to translate and find a web site you have

entered. The following window allows you to set two DNS servers by their IP addresses and these IP

addresses should be supplied to you by your ISP.

To configure the DNS for the Router, use the DNS Relay Selection pull down menu to select the DNS

configuration for the router. There are three choices:

•

Disable DNS

– Selecting this option will disable the DNS function of your router.

•

Use Auto Discovered DNS Server Only

– This choice will enable the router to automatically

find the DNS Server for your setup.

•

Use User Discovered DNS Server Only

– This choice will enable the DNS Servers entered in

the Preferred DNS Server and Alternate DNS Server fields. These two IP addresses must be stated

to you by your ISP.

The router will first try the

Preferred DNS Server

to resolve a website’s URL IP address. If that IP

address fails to resolve the URL, the Router will then try the

Alternate DNS Server

. Your ISP must

provide this information to you. Click

Apply

to set the DNS configurations into the memory of the

Router.

Dynamic DNS

The Router supports DDNS, a service that maps Internet domain names to IP addresses. DDNS serves

a similar purpose to DNS in that DDNS allows anyone hosting a Web or FTP server to advertise a

public name to prospective users. Unlike DNS that only works with static IP addresses, DDNS works

with dynamic IP addresses, such as those assigned by an ISP or other DHCP server. DDNS is popular

with home network users, who typically receive dynamic, frequently-changing IP addresses from their

service provider. To use DDNS, one simply signs up with a provider and installs network software on

their host to monitor its IP address. Please see your ISP for further information.

UPnP

UPnP supports zero-configuration networking and automatic discovery for many types of networked

devices. When enabled, it allows other devices that support UPnP to dynamically join a network,

obtain an IP address, convey its capabilities, and learn about the presence and capabilities of other

devices. DHCP and DNS service can also be used if available on the network. UPnP also allows

supported devices to leave a network automatically without adverse effects to the device or other

devices on the network. UPnP can be supported by diverse networking media including Ethernet,

Firewall, phone line and power line networking.
