    Netflow blocked by Firewall

    sprakash

      We have installed NTA 4 and NPM at our network. We have configured our cisco router to send the Netflow packets to our NTA server. In NTA server we have added router ports for netflow monitoring.

       

      We have a watchguard firewall configured in between the router and NTA server. Netflow packets are not reaching the NTA server because of the firewall.

       

      When we try to capture the Netflow using the Wireshark tool Netflow packets generating from router. we have allowed UDP/TCP 2055/161/162 ports in our firewall still the Netflow Packets are blocked at our firewall. Please help me to configure Netflow.
