Hello,
I have following application: Two GPS-System need to have a data connection. One is a Rover an one is the Base station. The Base station and the Rover shut be moveable.
For this I want to connect two TRB 140 via a VPN. The device can be used as an VPN server and client. Multiple connections are also possible. This should create the possibility of opening a second tunnel to one of the two endpoints for maintenance purposes.
Now I would like to use a SIM card from a provider without a static IP. The provider now assigns an IP to the gateway (TRB140) (WAN provider). If I now use a DDNS, the IP of the provider is transmitted. A client from the same WAN can theoretically connect without any problems.
How is it possible to establish a connection from an external IP4 (Landline) address to an TRB140 working as a server? What is the easiest way? Is this the right device for me?
Thank you in advents.
Greetings
Stephan
