DHCP Server Settings
DHCP stands for Dynamic Host Control Protocol. The DIR-855 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-855. 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 pool.

DHCP Reservation
If you want a computer or device to always have the same IP address assigned, you can create a DHCP reservation. The router will 
assign the IP address only to that computer or device. 
Note: This IP address must be within the DHCP IP Address Range.
Check this box to enable the reservation.
Enter the computer name or select from the drop down 
menu and click

Section 3 - Configuration
The DIR-855 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 Net\
work). 
The  DIR-855  firewall  feature  filters  out  unrecognized  packets  to  protect  your  LAN  network  so  all  computers  networked  with  the 
DIR-855 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-855 redirects the external service request to the appropriate 
server within the LAN network. 
The DIR-855 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.
