One other thing you might double check is whether or not any consumer
equipment (cable modem, router) has a firewall setting that could be
interfering.

My newest router came with a built-in DDOS protection feature, which
caused me some difficulty with UDP applications until I disabled it. The
default threshold for UDP was something like 200 or 300 pps. The manual
isn't clear on how the "protection" works, but I assume it starts
dropping packets on the floor when the threshold is exceeded. I turned
off that feature and the problem went away.

Apologies if you've already looked into this; long thread and I'm
jumping in late.
