I want to monitor the traffic from one of my pc's on the network. So I've got this plugged into port 3 of the draytek

Under Lan > switch > mirror I've got mirroring port as 4 and 3 where pc I want to monitor is plugged in.

I've got smart monitor on port 4 and it's not the picking the traffic up as there should be plenty of ftp traffic

Nobody???

In the end I gave up as it clearly wasn't working.

I installed smartmonitor on the pc concerned which was okay but couldn't get a report of it as it wasn't powerful enough to run it.
