Virtual Server 
The Virtual Server Configuration page allows users to set the configuration of Virtual Server. The 
firmware includes the Free BSD version firewall. All UDP/TCP ports are protected from intrusion. If 
any specific local PCs need to be mapped to the UDP/TCP port on WAN side, please input the 
mappings here. 
This product’s NAT firewall filters out unrecognized packets to protect your Intranet, so all hosts 
behind this product are invisible to the outside world. If you wish, you can make some of them 
accessible by enabling the virtual server.  
The Virtual Server allows you to set up public services, such as a Web server, FTP, E-mail etc. that 
can be accessed by external users of the Internet. Each service is provided by a dedicated network 
computer configured with a fixed IP address.   
Set up private network computers to act as servers and configure each server with a fixed IP address. 
Enter the desired service port numbers in the public port and private port field and specify port type as 
TCP or UDP.
