I am trying to use the Traffic Flow setup to export flows to a FlowTraq server. I have used it in the past on RouterOS with no problems, but on my newest routers RouterBOARD 750G r3 running 6.38 I am having problems getting it to report the correct traffic. In the setup I have it set to report flows from the ether2-master interface. I am using src-nat for all hosts connecting via the ether2 interface with a public address that is in my public subnet which is connected to ether1. I would expect to only see flows that have one of my inside private addresses listed as the source or destination. Instead I am also seeing flows that have the nat’d address as the source. I do not have this problem on an older router 751U-2HnD running 6.27 If the flows are reported with the nat’d address as the source it is impossible to find out which actual inside host is the source of the traffic.
