Hi, It has never been used, you do not need to set it up. It just shows the public IP as info.

FYI.
I could not reach my new v2.81 RRC over the internet.
Downgraded the RRC firmware back from 2.81 to 2.78.
Entered my fixed IP in "Extern IP/Host" under IP settings, and it was online again.
(did not change anything in router,etc)
I still don't seem to understand how fixed IP is implemented in fw2.81...
