Configure No-IP Dynamic DNS on Digi TransPort

When using a Digi TransPort Router with a Public SIM card, the issue of reaching this device by it's IP address happens as most/all providers will dynamically assign IP addresses that will change at every connection / reconnection.

To overcome this problem, it is possible to use a Dynamic DNS host configured in the router. The Router will update the service provider with it's current IP Address and / or any IP Address changes. This will allow the device to be reached without knowing it's currently assigned IP Address

Digi TransPort Routers currently supports 3 service providers type :
- DynDNS.org
- No-IP.org
- Other

In this example, No-IP.org will be used as they allow registration of free Dynamic DNS hosts.

Before you can successfully register the IP address of your router with a service provider, you must create an account on their web site. In this example, no-ip will be used.

1- Sign-UP for a Free Account on No-IP

Go to https://www.noip.com/sign-up and sign-up for a free DDNS Account. When registering, the "hostname" will be the name used to reach your device, for example: "digitesteu.ddns.net"
