7.      How do I configure remote access via DynDNS on a CM685V or a CM820V router?

DDNS feature allows a dynamic public IP to be used with the modem, and a fixed domain name is allocated (acquired thru a DNS service provider) to enable remote access from anywhere.

IMPORTANT:

DynDNS requires a SIM card enabled with a public IP, either dynamic or static. Please contact your network service provider to setup this feature.

To set DDNS service, go to Services > DDNS:

 

Required input:

Username       :                 DDNS username

Password    :                    DDNS password

Hostname/ Domain   :      domain name assigned to your modem

Note:

Prior to acquiring the DDNS name to be assigned to your modem, you need to sign up for the DDNS service. In the example below, we use www.dyn.com :

  1. Login to the web service www.dyn.com and sign up for the service to create your user account.
  1. Add/create the DDNS name that will be assigned to your modem.

  1. Enter the DDNS name and IP details of your modem. The IP address will be the public IP address assigned by the network service provider (i.e. Telstra). You can view this parameter on the status page of your modem user interface.

16.        How to obtain a public IP on your SIM card?

Telstra:

The common APN for a Telstra SIM is 'telstra.internet' which generates a dynamic private IP address. To enable your SIM for a dynamic public IP, you need to contact Telstra Customer Support Service on 125 111 and ask them to add the code 'GPTEXB3' to your SIM account. Once the SIM card enabled, change the APN on your router to 'telstra.extranet'. A post-paid account with Telstra is required.

Optus:

The common APN for an Optus SIM is 'connect' which generates a dynamic private IP address. To enable your SIM for a dynamic public IP, please ask Optus to activate public IP on your SIM account, then change the APN on your router to 'yesbusinessip'. A business account with Optus is required.

Vodafone:

Vodafone doesn’t offer a public IP on their SIM cards.
