Hi Tony, I am back to this problem. Are you sure you are using the latest version of PRTG? I have setup PRTG v18.104.22.1682 along with BWM v2.9.7 and on Windows XP x86 SP3 and it was working perfectly with a sniffing sensor:
I have done a few tests, and the PRTG sniffer previously showed the traffic for all PC's on the LAN side of the PC running Softperfect. Now it only shows the traffic going to the gateway PC running Softperfect. Eg if you download something to that PC it will show as traffic on PRTG, however if you download to a PC who's traffic flows through Softperfect, it does not show, but did so on pre 2.9 versions of Softperfect.
