The DIR-655 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-655 firewall feature filters out unrecognized packets to protect your LAN network so all computers networked 
with the DIR-655 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-655 redirects the external 
service request to the appropriate server within the LAN network. 
The  DIR-655  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.

QoS Engine
This option is disabled by default. Enable this option for better 
performance  and  experience  with  online  games  and  other 
interactive applications, such as VoIP.
This option should be enabled when you have a slow Internet 
uplink.  It  helps  to  reduce  the  impact  that  large  low  priority 
network packets can have on more urgent ones.
This option is enabled by default when the QoS Engine option 
is enabled. This option will allow your router to automatically 
determine the uplink speed of your Internet connection.
This displays the detected uplink speed.
The speed at which data can be transferred from the router to 
your ISP. This is determined by your ISP. ISP’s often speed 
as a download/upload pair. For example, 1.5Mbits/284Kbits. 
Using this example, you would enter 284. Alternatively you can 
test your uplink speed with a service such as www.dslreports.
com.
By default, the router automatically determines whether the underlying connection is an xDSL/Frame-relay network or some 
other connection type (such as cable modem or Ethernet), and it displays the result as Detected xDSL or Frame Relay Network. 
If you have an unusual network connection in which you are actually connected via xDSL but for which you configure either 
“Static” or “DHCP” in the Internet settings, setting this option to xDSL or Other Frame Relay Network ensures that the router 
will recognize that it needs to shape traffic slightly differently in order to give the best performance. Choosing xDSL or Other 
Frame Relay Network causes the measured uplink speed to be reported slightly lower than before on such connections, but 
gives much better results. 
When Connection Type is set to automatic, the automatically detected con\
nection type is displayed here.

The QoS Engine option helps improve your network gaming performance by prioritizing applications. By default the 
QoS Engine settings are disabled and application priority is not classified automatically.
