There are two zones on the firewall, namely, DMZ and an Inside Zone.

In DMZ Zone, PRTG is running and where as Inside Zone is hosting all windows machines.

I have added all the windows machines into PRTG Network Monitor using WMI and the issue is with DCOM ports.

I have to open all the DCOM ports range from 1025-65535 from PRTG to Windows Machines and, if I go to reduce DCOM ports then some of the PRTG sensors is not working.

I want to reduce the ports to be opened in the firewall.

Kindly help me please.... :(

dcom firewall prtg13 wmi

Hi,
in your case you might consider using remote probes as these would only require one opened port in your firewall. The probe would do the monitoring within your internal zone and send the data to the PRTG Core in the DMZ.
Best regards
