Here are my 2 biggest issues with R81.20 on the gateway from all the testing done in my lab. Again, just speaking for myself, maybe others have different experience.
1) Https inspection is very inconsistent, to put it nicely : - ). What I mean by that stement is following...say you block gambling category, k great, you go to olg.ca, gets blocked, fantastic. Then, 5 mins later, you refresh the page, same browser (mozilla), page is all "scrambled" and NOT blocked. You do same in Edge or chrome, works fine no matter how many times you refresh. Come back say 1 hour later, its the other way around, and even if I reset the browser, may work for 5-10 mins and again same problem. This NEVER used to happen back in R81.10 lab I had inspection on. By the way, its totally unrelated to my windows PC I tested with, as windows fw is disabled and I even tested brand new windows machine, exact same problem
2) Autonomous threat prevention is not working right at all. I had email chain last year with few people in R&D who told me that reason for why this was the issue back in R81.10 was amount of ram (I was very suspicious of that logic even back then), so to prove my point, I "slapped" on 32 GB of ram on R81.20 gw as they suggested, exact same problem...causes gw to "get stuck" when autonomous threat prevention is on, policy push is super inconsistent, but as soon as I disable this feature and go to having say only ips blade on, no issues even with 16 GB of ram installed.
But, in all fairness, other than these 2 issues, everything else seems fine, so who knows, maybe things get better with next jumbo, I have no idea...will have to wait and see 😇
