Netflow Analyzer - What ports does it use?
Hi, I have put the Netflow commands onto my Cisco 2600 router. This router is our Internet router and is in front of our Cisco firewall. The Netflow destination is a server in my LAN, so I was wondering what ports I need to open from this Internet router to my internal Netflow server? All I have opened is UDP 9996 from the router to the server on the LAN and nothing else. Do I need to open UDP 9996 from the Netflow server to the router?
Many Thanks
