Ubuntu Networking :: Traffic Monitor - How Much Data Downloaded/uploaded On An Interface This Month And Previous Month

I'm looking for a powerful network traffic monitor that can do all of the following (or at least a combination of tools that can do the following):

Tell me how much data was downloaded/uploaded on an interface this month and the previous month tell me how the traffic was used throughout the monthshow which internal IPs (IPs in the 192.168.1.0/24 network) used how much traffic show which ports/protocols on those IPs used all that traffic

Hhow LIVE traffic flow statistics that can tell me total speed of traffic going through an interface as well asshow which internal IPs (IPs in the 192.168.1.0/24 network) are using how much of the traffic show which ports/protocols on those IPs are using that traffic

This tool will run on a linux router through which all my internal PCs are connected to the Internet. This means the tool(s) need to work with NAT (traffic being forwarded and not necessarily destined for the interfaced being monitored).

The distribution being run doesn't have a package manager so any packages or dependencies have to be manually compiled and SCPed over file by file. For this reason, the tool/tools need to be simple (things like vnstat, not things like ntop that have their own web interface).

I know that vnstat can tell me the first bullet point so it's only there incase there's a tool out there that can do everything. If there's a tool that can only do the second or third bullet point, that's great too - I'll just keep using vnstat and look for something else to do the other task.
