Chapter 7 Management Tab Failure Count To Reboot Enter the fail count of ICMP echo request. If the device sends the specified count of ICMP echo requests to the host and none of the corresponding ICMP echo response packets is received, Ping Watch Dog will reboot the device. The default value is 3. Dynamic DNS The main function of Dynamic DNS (DDNS) is mapping the fixed domain name to dynamic IP address. When a device connects to the Internet through PPPoE or Dynamic IP, the WAN IP address it gets is not fixed, which is inconvenient for the Internet users to access the servers in the local area network through IP address. Dynamic DNS function allows users to access servers using a fixed domain name. The DDNS server will establish a mapping table about the dynamic IP address and the fixed domain name. When the WAN IP address of the device changes, it will make an update request to the specified DDNS server, and then the DDNS server will update the mapping relation between the IP address and the domain name. Therefore, whenever the WAN IP address changes, users on the Internet can still access the servers in the local area network using a fixed, easy-to-remember domain name. The DDNS function that serves as the client of DDNS service must work with DDNS server. Please register an account to DDNS service provider (NO-IP, Dyndns or Comexe) before using this function. Service Provider Dynamic DNS Select your DDNS service provider from the available DDNS service providers including NO-IP (www.no-ip.com), Dyndns (www.dyndns.com) and Comexe (www.comexe.net). Check the Enable box to use the function.  User Name - Enter the user name of the DDNS account.  Password - Enter the password of the DDNS account.  Show - Check the box to display the password characters.  Domain Name -Enter a customized domain name. Even if your IP is dynamic, other users on the Internet can still access your server via this fixed domain name after enabling the DDNS function. - 73 -

Dynamic DNS
The main function of Dynamic DNS (DDNS) is mapping the fixed domain name to dynamic IP address.
When a device connects to the Internet through PPPoE or Dynamic IP, the WAN IP address it gets is not
fixed, which is inconvenient for the Internet users to access the servers in the local area network through IP
address. Dynamic DNS function allows users to access servers using a fixed domain name.
The DDNS server will establish a mapping table about the dynamic IP address and the fixed domain name.
When the WAN IP address of the device changes, it will make an update request to the specified DDNS
server, and then the DDNS server will update the mapping relation between the IP address and the
domain name. Therefore, whenever the WAN IP address changes, users on the Internet can still access the
servers in the local area network using a fixed, easy-to-remember domain name.
The DDNS function that serves as the client of DDNS service must work with DDNS server. Please register
an account to DDNS service provider (NO-IP, Dyndns or Comexe) before using this function.
Service Provider
