@SergeCaron This is the result of a configuration error. Mine, of course!
The "Disable Gateway Monitoring Action" option was checked on the Tier 1 Gateway on Box #1.
Clearing this option, everything is working as expected on both boxes.

Thank you @jimp
That helps clarify quite a bit. There really isn't much available about the "Skip Rules" setting.
Based on the documentation, your answers are what I expected, but I wanted to be sure.
Thanks again,
Josh
