I know there have been a few other posts about this and I am sorry for adding one more, but I am confused as what I need to do to stop this.
You cannot "stop this". Can you stop people from sending you junk mail? Can you stop robocalls? All you can do is not respond to them, which is what the Orbi firewall is doing. The log indicates that the firewall rules identified a pattern in connection attempts that fit the criterion that some engineer within Netgear classifies as an "attack".
The router can be told to stop logging on the Advanced Tab, WAN Setup. "Stop Port Scan and DOS Protection." I record the logs from two Orbi systems and they both record about 60 of these "attacks" every day. Yet devices never lose internet.
Something is clearly wrong if every device connected to the Orbi loses internet at the same time. What specific ISP device is the Orbi connected to? (make and model)
firmware version: V2.7.2.102. And it is connected directly into my fiberoptic modem. It's a 716GE-I R2 Calix. Side Note - I am not using the Netgear Armor. Would that stop it from kicking everything?
Internet was solid using the basic router that CenturyLink gave me. ZyXel C1100Z. Never got kicked. Upgraded to Orbi and nothing but problems.

I cannot imagine how Armor would do anything in this situation. (But then, I have not activated Armor.)

A potential solution would be to reinstall the CenturyLink router (disable WiFi on it), then convert the Orbi to Access Point mode.
So I did this and it looks like the Orbi is still dropping. This would mean my router is probably a "lemon" correct? I would think that it in AP mode there would be no other reason for it to keep dropping. I also switched out power cables just in case...... Any other ideas or time to replace?
I forgot to ask how old this Orbi system is. Netgear provides 90 days of "complimentary support" and then a 1 year hardware warranty.
What happens if you put the ISP router back online as your host router and configure the RBR for AP mode?

Set it up in AP mode and Orbi router continued to restart as well.
Called support and opened a case with them. Here is what they have tried so far:
Factory Reset - Continued to restart
Changed channel - Continued to restart
Downgraded to 2.3.5 firmware - Continued to restart
I have also tried other power cables from my orbi satellites. I have changed power outlets, even moved it to a completely different floor. Have tried firmare versions 2.7, 2.5 and 2.3.
Starting to think they are going to make me try every random thing under the sun before they replace. Anyone got any other things I should try?
Ask about an RMA.
