Configuring a Free DDNS

Dynamic DNS (DDNS or DynDNS) is a method of automatically updating a name server in the Domain Name System (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information.

Use:
If you do not have a static public IP, but you want access your local resource, server, CCTV from outside world then you have to use ddns service.

There are multiple providers like dyn.com , noip.com etc, But these are paid ddns provider. If you want to go for free then you can use dyndns.co.za . 

Prerequisite:
1. Internet connection with a configurable modem.
2. Modem username & password.

4. A email id (to activate ddns service)

Step 1

i> Open dyndns.co.za in your browser

Service Provider : gnudip
Host Name : www.dyndns.co.za
Service Port : 3459
Domain name: <your dyndns username>.dyndns.co.za (eg tarz is my username so tarz.dyndns.co.za will be my domain name)
Username: your dyndns username
Password:  your dyndns password

Apply the changes.


Step 3
i> Open dyndns.co.za , login with your username & password (domain name is dyndns.co.za) Note: Make sure you logged in from the same network of your modem

Thats it... Now login to your modem & do port forwarding as like static ip.

Instead of your static ip you need use <dyndns username>.dyndns.co.za , ie in my case tarz.dyndns.co.za.
