    NTA 3.10 with ASA 5505 8.2(4) - no received netflows


      I have downloaded a trial version of Solarwinds NTA 3.10.0 and am attempting to collect Netflow from an ASA 5505 running 8.2(4)4. I have followed the instructions in the KB for "Configuring Cisco ASA devices for use with Orion NTA", have managed all Cisco ASA interfaces in Orion and added them all as monitored sources in NTA and been through the document "Best Practices for Troubleshooting NetFlow".


      A Wireshark trace running on the PC where the Orion trial NPM and NTA is running shows the Netflow (CFLOW) packets arriving form the ASA - the templates are present but with just "Flowset 1" showing in the trace. The NTA shows it has never received a Netflow packet from the ASA. I have been through the previous KB cases relating to ASAs with NTA. I have included the ASA 5505 Netflow configuration below and an output showing the flow export counters. Has anyone else seen this issue? Could it be an issue with running the trial software on a PC/laptop as opposed to a server?
