monitor the Internet activity

In the past based on the document below I have configured Netflow on the inside interface of the Internet router. This is the interface that connects your router to your switch.

Here is a link to configure netflow

http://www.cisco.com/en/US/docs/ios/12_1/switch/configuration/guide/xcdnfc.html

Place this on the router not the ASA.  The flow will then be applied to the exit interface on the router that is connected to the ASA.  Then any traffic outbound through the ASA will be cached and data collected for netflow

Re: monitor the Internet activity

You would apply this to the interface connected to your internet segment

This will walk you through a set-up and where.

If you have a Ethernet handoff from the ISP then you will apply to the Ethernet interface connected there.  You would not do any inside interface.  This is for WAN, not to assume that you cannot do netflow on your LAN.
