How does access to an LTE connection work via a public IP address?

The mdex LTE package allows for the seamless upgrade of LTE connections to provide for external access. For this, the MX200 VPN router included in the delivery is connected to the LAN port of the existing LTE router. The mdex router assigns the LTE connection a public IP address and establishes a connection to mdex. This allows all connections to this public IP address to be forwarded by mdex to the desired terminal device (e.g. server).
