DSL backup for external server access via a fixed public IP address

DSL backup for external server access via a fixed public IP address

With the mdex LTE Pro Package you can configure a fallback solution for your DSL connection that reroutes all internet traffic and external requests over the mobile network connection in the event of a loss of DSL connection.

If the DSL connection is in failure-free operation, remote access to the server takes place via the DSL connection’s fixed public IP address. If however the DSL connection should be lost, the mdex router automatically switches to the LTE mobile network connection. Then the server is accessible via a fixed public mobile network connection IP address.

mdex solution: mdex LTE Pro Package

How it works

This DSL backup solution involves an mdex mobile router being placed between the server and the DSL router. In the mdex router WAN fallback settings the DSL connection is set as the primary internet connection and the LTE mobile network connection as a secondary internet connection. Then the mdex router establishes an internet connection via the DSL connection. Remote access takes place via a fixed public DSL port IP address.

If a loss of DSL connection should occur here, the mdex router automatically establishes the internet connection via the LTE mobile network connection. The server is then accessible via a fixed public mobile network connection IP address. As soon as the DSL issue has been rectified, the mdex router automatically returns to using the DSL connection.

You can find further information on how this works and about the DSL backup configuration on our >> Support-Wiki.
