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.

Section 3 - Configuration
Tick  the  checkbox  to  enable  SPI.  SPI  (Stateful 
Packet  Inspection,  also  known  as  dynamic 
packet filtering) helps to prevent cyber attacks by 
tracking more state per session. It validates that 
the traffic passing through the session conforms 
to the protocol.
If an application has trouble working from behind 
the  router,  you  can  expose  one  computer  to 
the  Internet  and  run  the  application  on  that 
computer.
Note:  Placing  a  computer  in  the  DMZ  may 
expose  that  computer  to  a  variety  of  security 
risks.  Use  of  this  option  is  only  recommended 
as a last resort.
Use this section to restrict external IP addresses 
and  applications  from  accessing  your  network. 
This section also allows you to control the hosts/
applications  that  internal  network  devices  can 
have access to on the Internet. 
Firewall Settings
A firewall protects your network from the outside world. The D-Link DIR-685 offers a firewall type functionality. The SPI 
feature helps prevent cyber attacks. Sometimes you may want a computer exposed to the outside world for certain 
types of applications. If you choose to expose a computer, you cam enable DMZ. DMZ is short for Demilitarized Zone. 
This option will completely expose the chosen computer to the outside wo\
rld.
