• Chris Breen:
  @jeffporten Yeah, been up and down the router.

@BodyofBreen What were you dicking around with in the first place?

• Chris Breen:
  @jeffporten Switched to other Ethernet port on Mac Pro. Works!

@BodyofBreen I think @glennf had it right: gremlins. And maybe a bad/glitched Ethernet card.

• Chris Breen:
  @jeffporten @GlennF I really appreciate your help Jeff. Inspires me as a troubleshooter and human.

@BodyofBreen @glennf My pleasure. You caught me at a good time—procrastinating on a Saturday afternoon.
