Hi, I am trying to figure out how best to enable NetFlow on my router that's connected to DSL (PPPoE). My router has two physical interfaces and a dialer to connect to the DSL:
Which Interfaces do I need to enable NetFlow to get accurate NetFlow statistics without creating additional traffic or load on the router:
The inside physical interface, ingress, egress or both?
The outside physical interface (used by the dialer), ingress, egress or both?
The dialer interface ingress, egress or both?
Thank you for any help,
Ken
