4.5 DHCPD Configuration
DHCP is Dynamic Host Control Protocol. It can assign IP address to computers in the LAN automatically. For customers, it is not
easy to set TCP/IP protocol parameters to all LAN computers. There are IP address, subnet mask, gateway, DNS server and so
on. Problems can be solved easily by using DHCP. The system default is open. If customer doesn’t use DHCPD service, please
close this selection.

DHCP Server
Object
Description
Start IP, End IP
They are start and end addresses when DHCP server assigns IP automatically. After
setting IP address, internal computer received from this gateway is between these two
addresses
Note:
1. DHCP start IP and end IP are a must, and they are in the same subnet with gateway, but
can’t include gateway local IP ;
otherwise, DHCP server can’t work normally.
2. Lapped DHCP servers can’t be existed in the same LAN. If there are multi devices using DHCP server function in the same
LAN, it can cause IP address to unable to assign normally in the system. It needs to stop one DHCP server.
3. If PPPOE is used
, don’t use “local interface 1” DHCPD.
4.6 Dynamic Domain Name Server (DDNS) Configuration
DDNS stands for dynamic DNS, or more specifically dynamic Domain Name System. It's a service that maps internet domain
names to IP addresses. It's a DDNS service that lets you access your home computer from anywhere in the world. The gateway
provides DYNDNS, PLANET DDNS and Easy DDNS options.
