Hello,
my RB tries to establish a connection to 81.198.87.240:15252 UDP.
IP/Cloud DDNS and NTP are disabled.
I also disabled the SNTP client (System/SNTP Client)
Where does this come from?
I can remember that I had the same problem on other device but I can not remember which settings caused this problem.
I think it was the TimeZoneAutodetect flag in System/Clock. 
Haha, will the timezone be guessed by my IP address?

Exactly. You can drop unwanted outgoing traffic in output chain of firewall filter easily.
Yeah but since I have deactivated the automatic timezone checking there was no outgoing request.
