Setup Netflow with Comcast internet

I have an office that we just setup with comcast business internet. We have a cisco 871 router in place and the connection goes through our vpn concentrator. I setup netflow just like I did for our MPLS sites but I am not getting any flows. Has anyone been able to receive flows through a vpn connection?

Thanks

Here is the answer I was looking for:

flow record ipv4

match ipv4 protocol

match ipv4 source address

match ipv4 destination address

match transport source-port

match transport destination-port

match interface input

match interface output

collect counter bytes

collect counter packets

flow exporter test

destination x.x.x.x source vlan

output-features

transport udp 2055

template data timeout 60

flow monitor flow-monitor

record netflow-original

exporter test

cache timeout active 60

ip flow-export source Vlan

________________________________________________________

Under the interfaces add:

ip flow monitor flow-monitor input

ip flow monitor flow-monitor output

I have not tested this in several years, but it used to be that you couldn't export NetFlow through a "classic" IPSec tunnel (i.e., one configured with crypto maps on the physical interfaces). You had to use one of the other tunnel types, like an IPSec-encrypted GRE tunnel.

I do not know if this is still the case in more recent code versions.

Another thing to verify is that your export source VLAN is allowed into the tunnel.
