I have a need to find out  more info on where our data is going in and out of our network. My service provider has informed me that they can setup our routers to use Netflow for me, but I'd have to setup a Netflow server to receive the data. I know that PRTG can analyse the Netflow data, and i have installed that on a server. My question is, is this the only software I will need to capture and analyse the data? Or do I need addtitional software to actually receive the data?

Also both the router and software are asking me to nomintae a UDP port for the data exchange, is there standard port that should be used here?

actually, quick google search showed that there are no default port for that. every vendor has it's own

i saw 9995, 9555 and some other ports mentioned as default for different application.

do not worry about what other use. just pick one port, give it to your provider and set it in PRTG. do not forget to open firewall on that port for netflow traffic from your router
