    Netflow Top Applications only showing "IPsec Nat-Traversal"

    bunny

      Hello

       

      We have configured Flexible Netflow on a Cisco 871 router running version 12.4(20)T. The traffic is visible in the Orion Netflow tab, however the top conversations/applications show the following:

       

      Ingress...99.43% of traffic is "IPsec Nat-Traversal", with the top conversation being between the static WAN IP address of our router and an IP address in the PTT network.

       

      Egress...100% of traffic is "IPsec Nat-Traversal" between the same endpoints.

       

      Any idea why we cannot see the real conversations?

       

      Thanks

      Amy
