How is a Conexa SIM card accessible remotely?

Conexa SIM cards are characterised by their high redundancy, as they are equipped with two IP addresses. This dual IP addressing is a significant advantage that increases the reliability and stability of the connection. In the event of a failure or disruption of the primary IP address, a seamless switch to the secondary IP address occurs, ensuring continuity of service.

Remote access to a Conexa SIM card is achieved via a VPN connection to the primary or secondary IP address of the SIM card, depending on which one is currently active. When remote access is performed via the hostname, the currently active IP address is automatically addressed. 

Remote access via hostname (with VPN connection)

Remote access to a Conexa SIM card should preferably be done via the hostname so that the active IP address is always used. The hostname consists of the MSISDN of the SIM card and .LD.APNDNS.NET, for example: 8831906032000000.LD.APNDNS.NET

Example: 
Remote access to a Teltonika router with the Conexa SIM card, where remote access has been enabled via HTTPS port 4444:

1. Establish a VPN connection from your PC.
2. Open the web browser and enter the hostname: https://8831906032000000.LD.APNDNS.NET:4444
3. The WebUI login page of the Teltonika router will open. 

Determine active IP address (with VPN connection)

If an IP address is required for remote access instead of the hostname, the currently active IP address of the Conexa SIM card can be determined via the hostname using nslookup or ping as described below:

1. Establish a VPN connection from your PC.
2. Open the command prompt by typing "CMD" in the search box at the bottom of your Windows PC.

3. In the command prompt, the active IP address of the Conexa SIM card can be resolved by entering "nslookup <hostname>". The active IP address will then be displayed next to "Address", see example:

   C:\users\xxx>nslookup 8831906032000000.LD.APNDNS.NET
   
   Name: 8831906032000000.LD.APNDNS.NET
   Address: 100.xxx.xxx.xxx
   
   C:\users\

4. Alternatively to nslookup, you can send a ping to the hostname in the command prompt. The current IP address of the SIM card will then be displayed in square brackets, as in the following example:

   C:\Users\xxx>ping 8831906032000000.LD.APNDNS.NET
   
   Ping is executing for 8831906032000000.LD.APNDNS.NET [100.xxx.xxx.xxx] with 32 bytes of data:

Read hostname in 'DevicePro'

The hostname is displayed in DevicePro: 

Remote access via web.direct link (with DevicePro)

As an alternative to the VPN connection, remote access to an HTTP or HTTPS web server can be realised via the SIMPro function DevicePro using web.direct, for example, to access the WebUI of the mobile router. This method provides an efficient and user-friendly solution for remote access to web content without the need for a VPN connection.
