Netflow and PRTG
Posted on 2010-11-12
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?
