Before You Begin
It’s best to use a computer with an Ethernet adapter for configuring the DFL-1500. The
default IP address for the DFL-1500 is 192.168.1.254 (LAN1 at the port number 3)
with a Subnet Mask of 255.255.255.0. You will need to assign your computer a Static
IP address within the same range as the DFL-1500’s IP address, say 192.168.1.2 to
configure the DFL-1500. See the Appendix if you need assistance in assigning a
Static IP address for your network adapter.

Connecting the DFL-1500
A. First, connect the power cord to the Power Socket at the back panel
of the DFL-1500 and then plug the other end of the power adapter to
a wall outlet or power strip. Press the switch to ON position. The
Power LED will turn ON to indicate proper operation.
B. Using an Ethernet cable, insert one end of the cable to the WAN port
on the front panel of the DFL-1500 and the other end of the cable to a
DSL / Cable modem or other internet access devices.
C. Computers with an Ethernet adapter can be directly connected to any
of the LAN ports using a cross-over Ethernet cable.
D. Computers that act as servers to provide Internet services should be
connected to the DMZ port using an Ethernet Cable.

Using the Setup Wizard
A computer on your LAN1 must be assigned an IP address and subnet mask from the
same range as the IP address and subnet mask assigned to the DFL-1500 in order to
be able to make an HTTPS connection using a web browser. The DFL-1500 is
assigned an IP address of 192.168.1.254 with a subnet mask of 255.255.255.0 by
default. The computer that will be used to configure the DFL-1500 must be assigned
an IP address between 192.168.1.1 and 192.168.1.253 with a subnet mask of
255.255.255.0 to be able to connect to the DFL-1500. This address range can be
changed later. There are instructions in the DFL-1500 User’s Guide, if you do not
know how to set the IP address and subnet mask for your computer.
Step 1 －Login
Type “admin” in the account field,
“admin” in the Password field and
click Login.
Step 2 －Run Setup
Wizard
Click the Run Setup Wizard.
After login to DFL-1500 web configurator

type “http://192.168.1.254:8080”
or “https://192.168.1.254”into the
URL address box. Then press the
Enter or Return key.

Step 3 －System Name
Enter the Host Name and the
Domain Name, followed by clicking
the Next.
BASIC SETUP > Wizard
Step 4 －WAN
Connectivity
To setup the first WAN link, make
WAN1 as the Default WAN link
(Gateway/DNS). Choose the type
of IP Address Assignment
provided by your ISP to access the
Internet. Here we have four types to
select. This will determine how the
IP address of WAN1 is obtained.
Click Next to proceed.
BASIC SETUP > Wizard > Next
Step 4.a —DHCP client
If Get IP Automatically
(DHCP) is selected, DFL-1500 will
request for IP address, netmask,
and DNS servers from your ISP.
You can use your preferred DNS by
clicking the DNS IP Address and
then completing the Primary DNS
and Secondary DNS server IP
addresses. Click Next to proceed.
BASIC SETUP > Wizard > Next > DHCP
Step 4.b —Fixed IP
If Fixed IP Address is selected,
enter the ISP-given IP Address,
Subnet Mask, Gateway IP,
Primary DNS and Secondary
DNS IP. Click Next to proceed.
BASIC SETUP > Wizard > Next > Fixed IP

Step 4.c —PPPoE client
If PPP over Ethernet is
selected, enter the ISP-given User
Name, Password and the optional
Service Name. Click Next to
proceed.
BASIC SETUP > Wizard > Next > PPPoE
Step 5 －System Status
Here we select PPPoE method in
WAN1 port. Then the DFL-1500
provides a short summary of the
system. Please check if anything
mentioned above is properly set
into the system. Click Finish to
close the wizard.

Basic Setup
Setting up a VPN and configuring the Firewall on the DFL-1500 requires a deeper
understanding of the protocols and security features of the DFL-1500 than can be
presented here. If you need additional information about setting up a VPN or
configuring the Firewall, please consult your DFL-1500 User’s Guide or your Network
Administrator.
Please Note:
Each configuration page has buttons on the bottom labeled Apply and Reset. When
you configure any page, you must press the Apply button to make the configuration
effective. You CANNOT configure multiple pages, and then press Apply. Each page
must have the configuration information ‘applied’ before going on to the next page.
WAN Settings
The WAN Settings page allows you to modify the protocol that the DFL-1500 will use
to connect to your ISP and obtain the necessary network address information.
The usage of these pages is essentially the same as those introduced in the wizard
pages. The ISP Settings page allows you to modify the way that the DFL-1500 obtains
its network settings from your Internet Service Provider (ISP). The entry fields on the
page will change depending upon which of the following options you choose: Fixed IP
Address, Get IP Automatically, and PPPoE.
1. Fixed IP Address
If your ISP has assigned you an IP address that will never change, choose this option.
When this option is chosen, the following fields appear to allow you to enter the
network address information. The example shows that the ISP assigns an IP 61.2.1.1,
a netmask 255.255.255.0, a default gateway 61.2.1.254, and DNS (168.95.1.1).

2. Get IP Automatically
If your ISP uses the Dynamic Host Configuration Protocol (DHCP) to assign an IP
address, subnet mask, default gateway and DNS addresses, choose this option.

10
3. PPPoE
If your ISP uses Point-to-Point Protocol over Ethernet (PPPoE), choose this option.
When this option is chosen, the following fields appear to allow you to enter the
network address information:
To simplify the initial settings of the DFL-1500, the Network Address Translation is
automatically configured if the NAT Basic mode is selected. Then the DFL-1500
will let all private-IP traffic from the subnets of LAN/DMZ ports to access the
Internet using the global IP address assigned by the ISP.
