28D-Link DIR-615 User Manual
Section 3 - Conguration
The DIR-615 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-615 firewall feature filters out unrecognized packets to protect 
your LAN network  so  all  computers  networked  with  the  DIR-615  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-615 redirects the external 
service request to the appropriate server within the LAN network. 
The DIR-615 is also capable of port-redirection, meaning incoming traffic 
to a particular port may be redirected to a different port on the server 
computer.
On this page, 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.
If you are unsure of which port to open, check your application’s help file, 
FAQ, or technical support site. For a list of ports for common applications, 
please visit your local D-Link support website.
