1Services

1.1Overview

The Services module incorporates two functions, Dynamic DNS (DDNS) and UPnP (Universal Plug and Play) to provide convenient network services.

1.2Support Features

Dynamic DNS

Nowadays, network protocols such as PPPoE and DHCP are widely employed by ISPs to assign public IP addresses to users. The use of these protocols can cause the user’s public IP address to change dynamically. DDNS is an internet service that ensures a fixed domain name can be used to access a network with a varying public IP address. This means the user’s network can be more easily accessed by internet hosts.

UPnP

With the development of networking and advanced computing techniques, greater numbers of devices feature in networks. UPnP is designed to solve the problem of communication between these network devices. UPnP function allows devices dynamically discover and communicate with each other without additional configurations. For example, it allows the download of P2P software without opening ports.

4Configuration Example for Dynamic DNS

4.1Network Requirement

Host A gets internet services from an ISP (Internet Service Provider) via a PPPoE dial-up connection. The user wants to visit the router’s web management interface using another host on the internet.

Figure 4-1 Network Topology

4.2Configuration Scheme

For security management, the internet hosts attempting to manage the router must be permitted by the router. Remote Management is used to manage the IP addresses of these hosts.

Because the user uses PPPoE to access to the network, the public IP address of the router may be changed each time the dial-up connection is established. When the public IP address of the router changes, DDNS service ensures the DNS server rebinds the current domain name to the new IP address. This means the user can always reach the router using the same domain name, even if the public IP address has been changed.

4.3Configuration Procedure

4.3.1Specifying the IP Address of the Host

Before configuring DDNS, it is required to specify the IP address of the internet host for remote management. For details, go to System Tools > Admin Setup > Remote Management page.

4.3.2Configuring the DDNS function

There are four DDNS servers supported by the router, we take Peanuthull DNS as an example here.

1)Choose the menu Services > Dynamic DNS > Peanuthull and click Add to load the following page. Click Go to register to register a domain name on the official website of Peanuthull.

2)Set the Interface as WAN1, set the Update Interval as 6 hours, and enter the Account Name and Password previously registered before. Click OK.
