Hello,
which port is used by PRTG when running wmi queries against the operating system? Or in other words: which ports (tcp/udp) need to opened on the firewall to make PRTG running without any problems ?
Thanks for your quick response!

Hi,
there is no specification which ports are required by PRTG ion the target system as this fully depends on the protocol and type of sensors used. For a more detailed explanation, please see this article.
