4.6.3 Address Reservation
When you specify a reserved IP address for a PC on the LAN, that PC will always receive the
same IP address each time when it accesses the DHCP server. Reserved IP addresses should
be assigned to servers that require permanent IP settings. This page is used for address
reservation (shown in
Figure 4-24
).

,
DMZ
and
UPnP
. Click any of them, and you will be able to configure the
corresponding function. The detailed explanations for each submenu are provided below.
4.7.1 Virtual Servers
Virtual servers can be used for setting up public services on your LAN, such as DNS, Email and
FTP. A virtual server is defined as a service port, and all requests from the Internet to this service
port will be redirected to the computer specified by the server IP. Any PC that was used for a
virtual server must have a static or reserved IP Address because its IP Address may change
when using the DHCP function. You can set up virtual servers on this page, shown in Figure
4-27:
