External access to FLP

Hello Experts,

we have implemented a new FLP on S/4 which is reachable over the LAN as like:

https://<MyLocalHost>:44300/sap/bc/ui2/flp?sap-client=100&sap-language=EN

Now i would map these with an external adress to like:

https://<MyExternalHost>:44300/sap/bc/ui2/flp?sap-client=100&sap-language=EN

Do i just need to involve our network administrators to do so or are those mappings including work on SAP-side?

Hope you can provide me with some informations.

Best regards,

Volkan
