The Windows x86_64 MSI file for Packetbeat 8.3.2 won't work with default_route setting. I have found that if I compile the v8.3.2 source and swap the exe out for my compiled version that it works as expected. If I use the prebuilt MSI file I get the following error message:
Exiting: sniffer loop failed: Error starting sniffer: Error opening adapter: The system cannot find the device specified. (20)
Doh, I'm an idiot! Turns out I copied an older version I had prior to it being included in the released version onto my test machine. Yes, it works fine in 8.5. Thanks for the fast reply. Please close this thread.
