D-Link DFL-1500 [28/271] D link d link 20

Part I

Overview

D-Link 20

Step 1. Device IP Address

Setup the IP Address and IP Subnet Mask

for the DFL-1500.

Step 2. Client IP Range

Enable the DHCP server if you want to use

DFL-1500 to lease IP addresses to LAN PCs.

Specify the Pool Starting Address, Pool

Size, Primary DNS, and Secondary DNS that

will be assigned to them.

Example: in the figure, the DFL-1500 will assign

one IP address from 192.168.1.100 ~

192.168.1.119, together with the DNS server

192.168.1.254, to the LAN1 PC that

requests for an IP address.

Step 3. Apply the Changes

Click Apply to save. Now you can enable the

DHCP clients on your LAN1 PCs to get an IP.

BASIC SETUP > LAN Settings > LAN1 Status

Note: The IP Pool Starting Address must be on the same subnet specified in

the IP Address and the IP Subnet Mask field. For example, the addresses given

by the 192.168.1.100 with a pool size of 20 (192.168.1.100 ~

192.168.1.119) are all within the same range of 192.168.1.254 /

255.255.255.0

Step 4. Check NAT Status

The default setting of NAT is in Basic Mode.

After completing Step 3, the NAT is

automatically configured related rules to let all

private-IP LAN/DMZ-to-WAN requests to be

translated with the public IP assigned by the

ISP.

ADVANCED SETTINGS > NAT > Status

Step 5. Check NAT Rules

The DFL-1500 has added the NAT rules as the

right diagram. The rule Basic-LAN1 means

that, when matching the condition (requests of

LAN/DMZ-to-WAN direction with its source IP

falling in the range of 192.168.1.254 /

255.255.255.0), the request will be

translated into a public-source-IP requests, and

then be forwarded to the destinations.
