It's very easy to predict failure, and it's also very easy - after the fact - to say "I told you so." These are the "experts" and "gurus" speaking.
The "experts" are indeed expert in rhetoric because after one of their failure prediction ends up actually succeeding, they are quick to point of how it succeeded, often mentioning "luck"; and possibly pointing out the impeding failure.
What I would like to see the "expert" saying is who/what will succeed, and I have yet to find an "expert" who does that.
Interestingly enough, most of these "experts" are nothing more than professional writers/talker and don't actually do anything related to what they are talking about. I like the expression "Monday morning quarterback".
Can you SSH into your router and do an `iptables --list` ? I'm thinking that implementation uses the L7 chain. If that's the case then it may be a hair bit quicker using my implementation. Also, the REJECT rule is a bit cleaner than just dropping the packet, which I also suspect to be the case with "Access Restriction" implementation.
I can do iptables under the firewall settings, but ... it took me a while to find my way through this setting and I know it works, I tested by streaming YouTube content on AppleTV. I am going to leave it as it is.
If this workaround gets popular, I wonder if my provider (Comcast) and others will catch up and throttle youtube directly.
