Dynu.com DDNS configuration

Step 1. Dynu DDNS configuration

First of all we need to visit DDNS provider website - https://www.dynu.com, once we are here we have two options: create new user or use existing one.

If you do not have existing account click "Create Account"

To login into your account click "Login"

Enter your account details and press "Login"

Adding new host

You need to click "DDNS services"

Then "Add"

And finally you need to choose one of two options to use their domain name (red square) or your personal domain name (blue square) and click "Add"

After all these steps you should see this window

Step 2. Router configuration

To configure router we need to enter RUT homepage. To access it enter your router IP (eg. 192.168.1.1), into browser's URL bar. After that you should click "Dynamic DNS": Services -> Dynamic DNS

Then enter new configuration name and click Add new

After that you will see new line with two options "Delete" and "Edit". Click Edit

Dynamic DNS configuration

Once you have completed all steps before you will see window with important DDNS configuration settings. First of all, check "Enable" box

Next, you need to select service provider: Service, however our routers do not have Dynu as default provider, so you have to select custom.
After that it is important to create good "Custom update URL". It should look like this:
http://api.dynu.com/nic/update?hostname=[DOMAIN]&myip=[IP]&username=[USERNAME]&password=[PASSWORD]
DOMAIN -> your registered domain eg. teltonikademo.dynu.net
IP -> your IP address eg. 214.154.12.47
USERNAME -> your Dynu account username eg. teltonikademo
PASSWORD -> your Dynu account password eg. 28c7e9d80022be6f5c801cc9a7d0e13ee1647579df1f4911c7cfb6f0cca323f3
IMPORTANT use hash methods that covers your password for security reasons. You can do that here

Complete URL example: http://api.dynu.com/nic/update?hostname=teltonikademo.dynu.net&myip=212.47.100.158&username=teltonikademo&password=28c7e9d80022be6f5c801cc9a7d0e13ee1647579df1f4911c7cfb6f0cca323f3

Once you created URL you need to fill in last three fields:
Hostname -> your registered domain eg. teltonikademo.dynu.net
Username -> your Dynu account username eg. teltonikademo
Password -> your Dynu account password eg. xxxxxxxxxxxxx
And click "Save"

Remote access configuration

After you complete DDNS configuration last thing you need to do is to allow Remote access using HTTP. These options can be found System -> Administration -> Access control

And then click "Access Control" tab

Here you need to select "Enable remote HTTP access" option and press Save

Test your DDNS

Enter your hostname into browser and you should see something similar
