3.3.2.3 Table of fixed host entries

DHCP server can assign IP addresses and some options, such as gateway's IP address, DNS server, etc., to hosts in ESG-103's LAN side. Usually, DHCP server assigns IP addresses dynamically. However, you can assign MAC address and IP address to be one pair. When DHCP server receive request from that host whose MAC address is one of those pairs in its mapping table, DHCP server will assign that mapping IP address to host.

3.3.3 NAT/DMZ Setup

NAT is a mechanism that can convert your private IP addresses into a single public IP address. In ESG-103, we offer dynamic NAT, static NAT, and NAPT functions. Dynamic NAT means that you can assign a range of pri- vate IP addresses to map to a range of public IP addresses in the WAN inter- face. When one public IP address is mapped to one host, this public IP address could not be assigned to the other hosts. Static NAT means you can set up a private IP address and public IP address to be a pair. In ESG-103, you can set up to 5 set static NAT. This function is very similar to DMZ (demilitarized zone). In ESG-103, it also acts as "Virtual DMZ" host setting. NAPT is a special function of NAT. NAT records packet's Port and IP address, converts it into public IP address in the WAN side and gives this session one unique port number. Most of the famous applications are sup- ported by ESG-103 such as HTTP, FTP, Telnet, NetMeeting, RealPlayer, QuickTime, ....etc. NAT is a default function in ESG-103.
