Hello For all Mikrotik People there..!
i am looking for a method/way to prevent My Users to play PUPG during working hours
i know that is a difficult question to answer for, however i think that it must be a way out there to prevent such thing.
so lets consider this Question as an open one and i will be very happy to hear ideas from all of you.
PUPG servers are run in AWS cloud using many IPs, some unofficial lists are around, for ex here

Theoretically you could add all of them to an address list and filter them in you firewall.
But practically this will hardly work. The lists are unofficial, the IPs in the AWS cloud will change all the time and most likely you will also block other stuff as those AWS servers run a lot of other services beside PUPG servers.
And if employees play games during work hours, and if they do no-one notices lack of productive output, you probably have some problems in your company which should be solved in a different way than using firewalls.

Any employee at any place Ive worked has to sign a form stating they will use work only for work related items.
Often employers will allow employees some leeway, to do banking or browsing etc…
Gaming is verbotten, and the ‘contract’ signed should clearly state that repeated transgressions will cause TERMINATION.
That is how to deal with it… just need one example be made…
Corporate entities have edge appliance or intermediary firewall with IDP to block most sites that are not acceptable. Expensive equipment and expensive subscriptions, outside the context of MT routers.

That’s exactly what was meant with “different way than using firewalls” 
And blocking in companies depends in my experience on the region. Many US companies have not much filtering in place (if at all mostly “adult entertainment”), as they just can fire peoples caught on the spot.
In many European countries where even the lamest ass peoples can keep their jobs, filtering is much more popular.
In Germany anyway, because verboten and regeln is above anything there.
