One thing I can tell that the Garni 1025 is not a Fine Offset clone model like your Ambient ObserverIP WS-1002 - therefore the settings for your WS-1002 cannot be taken. It's a different manufacturer for the Garni 1025, CCL. When your Garni 1025 posts to WU, it probably posts only every 5 minutes, so it might not be astonishing that you don't receive anything with tcpdump, even if the settings look sensible. There is another option you may want to test which could give you the same results: your can download data from WU and import them into weewx using wee_import check the weewx documentation - weewx utilities guide
