I'm trying to get a QoS Round trip sensor working with a remote probe or a QoS reflector. I'd like to get figured out so I can use either a windows box at another site or config and ship a pi.
First: I'm a little confused on ports to open on my Cisco FireWall. I'm trying to connect my PRTG Server ( inside network ) and a Remote Probe on the outside of my FW.
I see references to both TCP 23560 and UDP 50000. But only see UDP 50000 in the Wireshark logs on the remote Probe. Do I need both those ports, opened on my end devices ( windows at this point in time ) forwarded to my PRTG Server as destination ports from the outside -> in?
Second question: I tried to do a PRTG Probe in QoS round trip Sensor settings, but I tested internal -> moved my windows box to another subnet and couldn't find where to update the Target Probe Dropdown menu.
