Chapter 4 System Tools - Planet Networking & Communication MH-5001 User Manual

MH-5001 User Manual
4.1 Demands
1. Basic configurations for domain name, password, system time, timeout and services.
2. DDNS: Suppose the MH-5001's WAN uses dynamic IP but needs a fixed host name. When the IP is changed, it is
necessary to have the DNS record updated accordingly. To use this service, one has to register the account, password, and
the wanted host name with the service provider.
3. DNS Proxy: Shorten the time of DNS lookup performed by applications.
4. DHCP Relay: It is to solve the problem that when the DHCP client is not in the same domain with the DHCP server, the
DHCP broadcast will not be received by the server. If the client is in the LAN (192.168.40.X) while the server is located in
the DMZ (10.1.1.4), the server will not receive any broadcast packet from the client.
5. The System Administrator would like to monitor the device from remote side efficiently.
6. Suppose our company applies three ISPs, but there are just two default WAN ports in the MH-5001. You hope to connect
the whole ISP links to the MH-5001.
4.2 Objectives
1. Configure the general properties, such as domain name, password, system time, and connection timeout correctly. Besides,
we can configure the prefered service name as the service name/numeric mapping list.
2. DDNS: By using the DDNS (Dynamic DNS), the MH-5001 will send the request for modification of the corresponding
DNS record to the DDNS server after the IP is changed.
3. DNS Proxy: Reduce the number of DNS requests and the time for DNS lookup.
4. DHCP Relay: Enable the DHCP client to contact with the DHCP server located in different domain and get the required IP.
5. Through the SNMP manager, we can easily monitor the device status.
6. We hope to customize the interface of MH-5001 to fit our requests.
4.3 Methods
1. Configure the domain name, password, system time, connection timeout and service name.
2. DDNS: Configure the MH-5001 so that whenever the IP of the MH-5001 is changed, it will send requests to the DDNS
server to refresh the DNS record. As the following Figure 4-1 demonstrated, the original WALL-1 has registered WAN1 IP
address "61.2.1.1" on the DDNS server (www.dyndns.org). It's domain name address is "me.dyndns.org". If the WAN1 IP
address is reassigned by the ISP. WALL-1 will update the registered IP address "61.2.1.1" as the assigned one. This is the
base mechanism of the DDNS.
This chapter introduces System Management and explains how to implement it.
