Advanced > Virtual Server
Using the Configuration Menu (continued)
The DI-624 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 DI-624 firewall feature filters out unrecognized packets to protect your LAN 
network so all computers networked with the DI-624 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 DI-
624 redirects the external service request to the appropriate server within the LAN 
The DI-624 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.
