How does access to a fixed public IP address work?

With the mdex public.IP, a fixed public IP address can be used to access mobile devices (e.g. LTE router) from the internet anywhere in the world. All connections to this public IP address are forwarded by mdex to the mobile terminal device on the mobile network. There are no restrictions when it comes to IP communication. All data is forwarded to the device transparently. This makes mdex public.IP ideal for applications that require worldwide online access, e.g. web servers, small business servers, VPN routers or network cameras.

Important notice!

A fixed public IP address means that your devices are accessible to anyone throughout the world. This means these devices are also exposed to typical online attacks. All mdex security barriers (firewall, protocol restrictions, VPN) are suspended in the interests of unrestricted IP communication. It is your responsibility to take the necessary security precautions.

Fixed public IP address for LTE

Depending on the application, there may be no alternative to a fixed public IP address.  If you want to run an e-mail server locally, you will for example require a fixed public IP address which is accessible externally on a permanent basis. If you are also intending to run the terminal device to be accessed in a rural area or a decentralised location, connection via a mobile network is often the only alternative since there is no DSL connection or the data throughput of the existing line is too little. Since the government-supported LTE network expansion, the mobile network has emerged as a serious DSL alternative, especially in rural regions. Added to this is the high data throughput rate which frequently reaches up to to 50 Mbit/s, qualifying the LTE standard for particularly bandwidth-intensive applications.
