The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for automating
the configuration of computers that use TCP/IP. DHCP can be used to automatically
assign IP addresses, to deliver TCP/IP stack configuration parameters such as the subnet
mask and default router, and to provide other configuration information.
This page shows the setting of WAN interface which is DHCP mode (Figure 4-10).

4.4.3 NAT
It’s separated into two parts: Virtual Servers, and DMZ Host.
4.4.3.1 Virtual Servers
Virtual Server allows you to direct incoming traffic from WAN side identified by Protocol
and External port to the internal server with private IP address on the LAN side. The
“Internal Port” can be modified if the “External Port” needs to be converted to a different
port number used by the server on the LAN side. The remote IP should be specified in the
table to allow the access. A maximum 50 entries can be configured. (Figure 4-11)
