DHCP Server Settings

DHCP stands for Dynamic Host Control Protocol. The DIR-685 has a built-in DHCP server. The DHCP Server will

automatically assign an IP address to the computers on the LAN/private network. Be sure to set your computers to be

DHCP clients by setting their TCP/IP settings to “Obtain an IP Address Automatically.” When you turn your computers

on, they will automatically load the proper TCP/IP settings provided by the DIR-685. The DHCP Server will automatically

allocate an unused IP address from the IP address pool to the requesting computer. You must specify the starting and

ending address of the IP address range.

Section 3 - Configuration

The DIR-685 can be configured as a virtual server so that remote users accessing Web or FTP services via the public

IP address can be automatically redirected to local servers in the LAN (Local Area Network).

The DIR-685 firewall feature filters out unrecognized packets to protect your LAN network so all computers networked

with the DIR-685 are invisible to the outside world. If you wish, you can make some of the LAN computers accessible

from the Internet by enabling Virtual Server. Depending on the requested service, the DIR-685 redirects the external

service request to the appropriate server within the LAN network.

The DIR-685 is also capable of port-redirection, meaning incoming traffic to a particular port may be redirected to a

different port on the server computer.

Each virtual service that is created will be listed at the bottom of the screen in the Virtual Servers List. There are

pre-defined virtual services already in the table. You may use them by enabling them and assigning the server IP to

use that particular virtual service.
