Thanks Ole, got it working after running the tests and digging through the test
code. I'm able to capture and parse the IPFIX output from the Flowprobe plugin.
I have another question. I'm going through the examples, specifically the
"Progressive Tutorial - Source NAT" and "VPP/Configure VPP As A Router Between
Namespaces".
I get the examples working as is, however they only allow ICMP traffic through,
TCP and UDP gets dropped somewhere and can't get through.
Do I need to change the setup to get TCP/UDP to go through?

Hi Johan,
You have a route to 192.168.65.2?
Nothing shows up in "show error"?
You can look at test/test_flowprobe.py
for examples. And you might also try a make test TEST=flowprobe to ensure
your build works.
On second pass on your configuration.
You have enabled flow collection in the L2 path, if you are IP forwarding
you need to enable it in the L3 path.
