    Setting Up Netflow  on Internet Router via Firewall



      From last few days i am trying to get the netflow logs from the new router 2921 to my Netflow servers but its not happening, currently ip have flow packet from c6500 series.

      There is one firewall between router and system. can anyone tell me what exact port numbers need to be open on the firewall to get the logs.

      Here is the diagram:

      internet router (2921)----FW-----c3560----c6500----Netflow server.


      i have created ACL permit udp port 161,162,2055,966 on router and open udp that port on the fw by fw team but flow still not hit.


      Do you have some tricky to solve this?
