Orbi RBE971: Selective website and DNS failures improved after disabling Protection Engine

PE was implemented a couple of years ago on Orbi. I an added security measure to prevent attacks against the router from external sources. Was first seen on Nighthawk routers. I remember some users on the NH routers posted seeing similar issues early on about when PE was enabled, odd issues were seen and disappeared after PE was disable. I believe over time, NG has make updates to PE and some adjustments. Possible similar issue could be seen on Orbi with PE. Not sure if some sites may be adding to this issue as well and some sites could be doing odd things to that PE maybe preventing, nefarious or not. Maybe a learning curve here too for PE. Something you can submit a support case about and let NG know about as this would be beyond forum help. PE was implemented behind the scenes on Orbi BE series however had no user UI. I asked about NG adding a UI for this very reason. 

Another reason was to ensure that users using the security testing site grc.com and it's shieldsup! test would start passing as prior versions of FW had not been passing there security test.
