SERVICES

DHCP Service
DHCP adopts Client/Server communication mode. The client sends a configuration request to Server which feeds back corresponding configuration information, including the distributed IP address to the Client to achieve the dynamic configuration of IP address and other information.

• DHCP Server must distribute IP address when the Workstation logs on and ensure each workstation is supplied with a different IP address. DHCP Server has simplified some network management tasks requiring manual operations before to the largest extent.
• As DHCP Client, the device receives the IP address distributed by DHCP server after logging in the DHCP server, so the Ethernet interface of the device needs to be configured into an
  automatic mode. To enable the DHCP service, find the navigation t ree, select Services >> DHCP Service, then enter “DHCP Service”

Table 3 3 1 Parameters of DHCP Service

DNS

(Domain Name System) is a DDB used in TCP/IP application programs, providing a switch between domain name and IP address. Through DNS, user could directly use some meaningful domain name which could be memorized easily and DNS Server in network could resolve the domain name into correct IP address. Manually set the DNS, use DNS via dialing if it is empty. Generally, it needs to be set only when a static IP is used on the WAN port. Click the “ Service >>Domain Name Service” menu in the navigation tree to enter the “Domain   Name Service” interface.

DNS (DNS Settings)

DNS Relay
CR202 works as a DNS Agent and relays DNS request and response messages between DNS Client and DNS Server to carry out domain name resolution in lieu of DNS Client. From navigation tree, select ” Service >>DNS Relay” menu, then enter “DNS Relay”

Table 3 3 3 DNS Transfer Parameters

CAUTION

• When enabling DHCP, the DHCP relay is also enabled automatically. Relay cannot be disabled without disabling DHCP.

DDNS
DDNS maps a user’s dynamic IP address to a fixed DNS service. When the user connects to the network, the client program will pass the host’s dynamic IP address to the server program on the service provider’s host through information passing. The server program is responsible for providing DNS service and realizing dynamic DNS. It means that DDNS captures user’s each change of IP address and matches it with the domain name, so that other Internet users can communicate through the domain name. What end customers have to remember is the domain name assigned by the dynamic domain name registrar, regardless of how it is achieved. DDNS serves as a client tool of DDNS and is required to coordinate with DDNS Server. Before the application of this function, a domain name shall be applied for and registered on a proper website such as www. 3322. org.
InRouter305 DDNS service types include QDNS (3322)-Dynamic, QDNS(3322)-Static, DynDNS-Dynamic, DynDNS-Static, DynDNS-Custom and No-IP.com. To set DDNS, click the “Service >> Dynamic Domain Name” menu in the navigation tree, then enter “Dynamic Domain Name” interface.
