I wonder if this has anything to do with the handling of GRE for
tunneling hotspot Wi-Fi traffic from their routers.
It wouldn't be the first time an ISP's handling of their own traffic
caused problems with a user's traffic, even though it shouldn't.

Thanks Eric and Brendan. Yes, this is specifically related to when we put
the rac2v1s in bridge mode and I bind one of the static public IP addresses
to my router. If I captured packets on my router I can see GRE packets
leaving my router destined for my data center, but I never see any of the
return packets I send. They are being lost/dropped on the way back in. I
am up to 30 of these now. What I can't grock is why they come in at a rate
of ~5 every morning. If anyone has any contacts at Spectrum that might
listen, or a workaround, please let me know!
