2) Virtual server
After NAT is enabled, the internal network devices cannot be accessed from the
Internet. To provide public services such as Web server, Email and FTP for the outside,
a virtual server needs to be configured to make the network computer with private static
IP address provide these services. Although the internal service address cannot be
accessed by external users directly, the DR814Q can identify service requests through
port number and forward them to the virtual server.
To configure a virtual server, click <Add Reserved Mapping…> in the [Reserved
Mappings] section (see Figure 5-13) to enter the page as below.
