I have a Juniper SRX-240 firewall with 13 active, physical interfaces. Interface #1 is the default route off the firewall to the internet. Five of the physical interfaces (each on its own subnet) on this firewall are customers. I need to know how much traffic (perhaps total bytes over a 7 day period) from these five customers utilize the internet connection on port 1 for bill-back purposes. I created IP Groups that define all the subnet on the firewall (customers and other subnet). I was hoping the NTA feature of SolarWinds would provide this, but support say it doesn't. I gotta believe there is a way. Unfortunately I cannot just look at what the traffic is on the five interfaces because there is traffic to/from these customers to other ports/interfaces other than port 1. I'm running NTA 4.0. Ideas??
