Internet Connection Setup Wizard
This wizard guides you through the following basic router setup steps:
  • Set your Password
  • Select your Time Zone
  • Configure your Internet Connection

WAN

The WAN (Wide Area Network) section is where you configure your Internet Connection type. There are several connection types to choose from: Static IP, DHCP, PPPoE, PPTP, L2TP, and BigPond. If you are unsure of your connection method, please contact your Internet Service Provider. Note: If using the PPPoE option, you will need to ensure that any PPPoE client software on your computers is removed or disabled.

Static WAN Mode
Used when your ISP provides you a set IP address that does not change. The IP information is manually entered in your IP configuration settings. You must enter the IP address, Subnet Mask, Gateway, Primary DNS Server, and Secondary DNS Server. Your ISP provides you with all of this information.
DHCP WAN Mode
A method of connection where the ISP assigns your IP address when your router requests one from the ISP's server. Some ISP's require you to make some settings on your side before your router can connect to the Internet.

Host Name: Some ISP's may check your computer's Host Name. The Host Name identifies your system to the ISP's server. This way they know your computer is eligible to receive an IP address. In other words, they know that you are paying for their service.

Use Unicasting: This option is normally turned off, and should remain off as long as the WAN-side DHCP server correctly provides an IP address to the router. However, if the router cannot obtain an IP address from the DHCP server, the DHCP server may be one that works better with unicast responses. In this case, turn the unicasting option on, and observe whether the router can obtain an IP address. In this mode, the router accepts unicast responses from the DHCP server instead of broadcast responses.

Enable BigPond: Check this option to connect to the internet through Telstra BigPond Cable Broadband in Australia. Telstra BigPond provides the values for BigPond Server, BigPond User Id, and BigPond Password.

PPPoE
Select this option if your ISP requires you to use a PPPoE (Point to Point Protocol over Ethernet) connection. DSL providers typically use this option. This method of connection requires you to enter a Username and Password (provided by your Internet Service Provider) to gain access to the Internet.

Dynamic IP: If your ISP has assigned a fixed IP address, select this option. The ISP provides the value for the IP Address.

Static IP: If the ISP's servers assign the router's IP addressing upon establishing a connection, select this option.

Service Name: Some ISP's may require that you enter a Service Name. Only enter a Service Name if your ISP requires one.

Reconnect Mode: Typically PPPoE connections are not always on. The D-Link router allows you to set the reconnection mode. The settings are:

  • Always on: A connection to the Internet is always maintained.
  • On demand: A connection to the Internet is made as needed.
  • Manual: You have to open up the Web-based management interface and click the Connect button manually any time that you wish to connect to the Internet.

Maximum Idle Time: Time interval the machine can be idle before the PPPoE connection is disconnected. The Maximum Idle Time value is only used for the "On demand" connection mode.

PPTP
PPTP (Point to Point Tunneling Protocol) uses a virtual private network to connect to your ISP. This method of connection is primarily used in Europe. This method of connection requires you to enter a Username and Password (provided by your Internet Service Provider) to gain access to the Internet.

Dynamic IP: If your ISP has assigned a fixed IP address, select this option. The ISP provides the values for the following fields: PPTP IP Address, PPTP Subnet Mask , and PPTP Gateway IP Address.

Static IP: If the ISP's servers assign the router's IP addressing upon establishing a connection, select this option.

PPTP Server IP Address: The ISP provides this parameter, if necessary. The value may be the same as the Gateway IP Address.

Reconnect Mode: Typically PPTP connections are not always on. The D-Link router allows you to set the reconnection mode. The settings are:

  • Always on: A connection to the Internet is always maintained.
  • On demand: A connection to the Internet is made as needed.
  • Manual: You have to open up the Web-based management interface and click the Connect button manually any time that you wish to connect to the Internet.

Maximum Idle Time: Time interval the machine can be idle before the PPTP connection is disconnected. The Maximum Idle Time value is only used for the "On demand" connection mode.

L2TP
L2TP (Layer Two Tunneling Protocol) uses a virtual private network to connect to your ISP. This method of connection requires you to enter a Username and Password (provided by your Internet Service Provider) to gain access to the Internet.

Dynamic IP: If your ISP has assigned a fixed IP address, select this option. The ISP provides the values for the following fields: L2TP IP Address, L2TP Subnet Mask , and L2TP Gateway IP Address.

Static IP: If the ISP's servers assign the router's IP addressing upon establishing a connection, select this option.

L2TP Server IP Address: The ISP provides this parameter, if necessary. The value may be the same as the Gateway IP Address.

Reconnect Mode: Typically L2TP connections are not always on. The D-Link router allows you to set the reconnection mode. The settings are:

  • Always on: A connection to the Internet is always maintained.
  • On demand: A connection to the Internet is made as needed.
  • Manual: You have to open up the Web-based management interface and click the Connect button manually any time that you wish to connect to the Internet.

Maximum Idle Time: Time interval the machine can be idle before the L2TP connection is disconnected. The Maximum Idle Time value is only used for the "On demand" connection mode.

Advanced

These options apply to all WAN modes.

Use These DNS Servers: This option should be enabled if your ISP requires you to enter the DNS Server information. You will then be able to enter a primary and secondary DNS server.

Use the default MTU: If this option is checked (the default case), the router selects the usual MTU settings for the type of WAN interface in use. If this option is unchecked, the router uses the value of the MTU option (which follows).

MTU: The Maximum Transmission Unit (MTU) is a parameter that determines the largest packet size (in bytes) that the router will send to the WAN. If LAN devices send larger packets, the router will break them into smaller packets. Ideally, you should set this to match the MTU of the connection to your ISP. Typical values are 1500 bytes for an Ethernet connection and 1492 bytes for a PPPoE connection. If the router's MTU is set too high, packets will be fragmented downstream. If the router's MTU is set too low, the router will fragment packets unnecessarily and in extreme cases may be unable to establish some connections. In either case, network performance can suffer.

WAN Port Speed: Normally, this is set to "auto". If you have trouble connecting to the WAN, try the other settings.

Respond to WAN Ping: If you leave this option unchecked, you are causing the public WAN IP address of the router not to respond to ping commands. Pinging public WAN IP addresses is a common method used by hackers to test whether your WAN IP address is valid.

WAN Ping Inbound Filter: Select a filter that controls access as needed for WAN pings. If you do not see the filter you need in the list of filters, go to the Advanced -> Inbound Filter screen and create a new filter.

MAC Cloning Enabled: Some ISP's may check your computer's MAC address. Each networking device has it's own unique MAC address defined by the hardware manufacturer. Some ISP's record the MAC address of the network adapter in the computer or router used to initially connect to their service. The ISP will then only grant Internet access to requests from a computer or router with this particular MAC address. Your new D-Link router has a different MAC address than the computer or router that initially connected to the ISP. To resolve this problem, the D-Link router has a special feature that allows you to clone (that is, replace the router's MAC address with) another MAC address.

MAC Address: If you have enabled MAC Cloning, you can either type in an alternate MAC address (for example, the MAC address of the router initially connected to the ISP) or copy the MAC address of a PC. To copy the MAC address of the computer that initially connected to the ISP, connect to the D-Link router using that computer and click the Clone Your PC's MAC Address button. The WAN port will then use the MAC address of the network adapter in your computer.

LAN

These are the settings of the LAN (Local Area Network) interface for the router. The router's local network (LAN) settings are configured based on the IP Address and Subnet Mask assigned in this section. The IP address is also used to access this Web-based management interface. It is recommended that you use the default settings if you do not have an existing network.

IP Address. The IP address of your router on the local area network. Your local area network settings are based on the address assigned here. For example, 192.168.0.1.

Subnet Mask. The subnet mask of your router on the local area network.

RIP Announcement. Used with multiple routers to broadcast routing information.

Router Metric. The metric or cost of the routes advertised in RIP announcements.

DNS Relay. When DNS Relay is enabled, the router plays the role of a DNS server. DNS requests sent to the router are forwarded to the ISP's DNS server. This provides a constant DNS address that LAN computers can use, even when the router obtains a different DNS server address from the ISP upon re-establishing the WAN connection. You should disable DNS relay if you implement a LAN-side DNS server as a virtual server.

DHCP

DHCP stands for Dynamic Host Configuration Protocol. The DHCP section is where you configure the built-in DHCP Server to assign IP addresses to the computers and other devices on your local area network (LAN).

Enable DHCP Server
Once your D-Link router is properly configured and this option is enabled, the DHCP Server will manage the IP addresses and other network configuration information for computers and other devices connected to your Local Area Network. There is no need for you to do this yourself.

The computers (and other devices) connected to your LAN also need to have their TCP/IP configuration set to "DHCP" or "Obtain an IP address automatically".

When you set Enable DHCP Server, the following options are displayed.

DHCP IP Address Range
These two values (from and to) define a range of addresses that the DHCP Server uses when assigning addresses to computers and devices on your Local Area Network. Any addresses that are outside of this range are not managed by the DHCP Server; these could, therefore, be used for manually configured devices or devices that cannot use DHCP to obtain network address details automatically.

It is possible for a computer or device that is manually configured to have an address that does reside within this range. In this case the address should be reserved (see Static DHCP Client below), so that the DHCP Server knows that this specific address can only be used by a specific computer or device.

Your D-Link router, by default, has a static IP address of 192.168.0.1. This means that addresses 192.168.0.2 to 192.168.0.254 (from 2 to 254) can be made available for allocation by the DHCP Server.

Example:
Your D-Link router uses 192.168.0.1 for the IP address. You've assigned a computer that you want to designate as a Web server with a static IP address of 192.168.0.3. You've assigned another computer that you want to designate as an FTP server with a static IP address of 192.168.0.4. Therefore the starting IP address for your DHCP IP address range needs to be 5 or greater.
Example:
Suppose you configure the DHCP Server to manage addresses From 100 To 199. This means that 3 to 99 and 200 to 254 are NOT managed by the DHCP Server. Computers or devices that use addresses from these ranges are to be manually configured. Suppose you have a web server computer that has a manually configured address of 192.168.0.100. Because this falls within the "managed range" be sure to create a reservation for this address and match it to the relevant computer (see Static DHCP Client below).
DHCP Lease Time
The amount of time that a computer may have an IP address before it is required to renew the lease. The lease functions just as a lease on an apartment would. The initial lease designates the amount of time before the lease expires. If the tenant wishes to retain the address when the lease is expired then a new lease is established. If the lease expires and the address is no longer needed than another tenant may use the address.
Always Broadcast
If all the computers on the LAN successfully obtain their IP addresses from the router's DHCP server as expected, this option can remain disabled. However, if one of the computers on the LAN fails to obtain an IP address from the router's DHCP server, it may have an old DHCP client that incorrectly turns off the broadcast flag of DHCP packets. Enabling this option will cause the router to always broadcast its responses to all clients, thereby working around the problem, at the cost of increased broadcast traffic on the LAN.
Number of Dynamic DHCP Clients

In this section you can see what LAN devices are currently leasing IP addresses.

Revoke: The Revoke option is available for the situation in which the lease table becomes full or nearly full, you need to recover space in the table for new entries, and you know that some of the currently allocated leases are no longer needed. Clicking Revoke cancels the lease for a specific LAN device and frees an entry in the lease table. Do this only if the device no longer needs the leased IP address, because, for example, it has been removed from the network.

Add/Edit DHCP Reservation

This option lets you reserve IP addresses, and assign the same IP address to the network device with the specified MAC address any time it requests an IP address. This is almost the same as when a device has a static IP address except that the device must still request an IP address from the D-Link router. The D-Link router will provide the device the same IP address every time. DHCP Reservations are helpful for server computers on the local network that are hosting applications such as Web and FTP. Servers on your network should either use a static IP address or use this option.

MAC Address: To input the MAC address of your system, enter it in manually or connect to the D-Link router's Web-Management interface from the system and click the Copy Your PC's MAC Address button.

A MAC address is usually located on a sticker on the bottom of a network device. The MAC address is comprised of twelve digits. Each pair of hexadecimal digits are usually separated by dashes or colons such as 00-0D-88-11-22-33 or 00:0D:88:11:22:33. If your network device is a computer and the network card is already located inside the computer, you can connect to the D-Link router from the computer and click the Copy Your PC's MAC Address button to enter the MAC address.

As an alternative, you can locate a MAC address in a specific operating system by following the steps below:

Windows 98
Windows Me
Go to the Start menu, select Run, type in winipcfg, and hit Enter. A popup window will be displayed. Select the appropriate adapter from the pull-down menu and you will see the Adapter Address. This is the MAC address of the device.
Windows 2000
Windows XP
Go to your Start menu, select Programs, select Accessories, and select Command Prompt. At the command prompt type ipconfig /all and hit Enter. The physical address displayed for the adapter connecting to the router is the MAC address.
Mac OS X Go to the Apple Menu, select System Preferences, select Network, and select the Ethernet Adapter connecting to the D-Link router. Select the Ethernet button and the Ethernet ID will be listed. This is the same as the MAC address.

Computer Name: You can assign a name for each computer that is given a reserved IP address. This may help you keep track of which computers are assigned this way.

Example:
Game Server
DHCP Reservations List
This shows clients that you have specified to have reserved DHCP addresses. An entry can be changed by clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and the "Edit DHCP Reservation" section is activated for editing.
