Netflow export issue


I am trying to export netflow data from a custumer router to my server, but i don't get any data.

The traffic isn't getting by my firewall, but if i do a traceroute the traffic goes to the server.

I had the same config in differente routers with no problem at all.

the IOS is different in this casa, as it is the only Version 15 i have with netflow.

The routers output:

sh ip flow export  

Flow export v9 is enabled for main cache

  Export source and destination details :

  VRF ID : Default

    Source(1) (Loopback15)

    Destination(1) (9995)

  Version 9 flow records

  279309 flows exported in 9619 udp datagrams

  0 flows failed due to lack of export packet

  0 export packets were sent up to process level

  0 export packets were dropped due to no fib

  0 export packets were dropped due to adjacency issues

  0 export packets were dropped due to fragmentation failures

  0 export packets were dropped due to encapsulation fixup failures

traceroute sou loop15 port 9995

Type escape sequence to abort.
