ADVANCED > VIRTUAL SERVER 
 
 
The DI-604 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 network.   
The DI-604 firewall feature filters out unrecognized packets to protect your 
LAN network so all computers networked with the DI-604 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-604 redirects the external service request to the 
appropriate server within the LAN network.   
The DI-604 is also capable of port-redirection meaning incoming traffic to 
a particular port may be redirected to a different port on the server 
computer.
