Our company wishes to block all online mmorpg and other such games. I really don't want to block ports as sometimes some of the ports are used by our programmers testing our those ports. Our company uses a Draytek 2820 modem and it can block ip ranges too.

Where can I find such a list? And if simply using IP's is a bad idea what is the best way to block MMORPG's?

Would you not be better to block all and just open the ports that you do need or is this not possible? – Dave Sep 7 '12 at 9:17
I would try talking to the employees. Simply as it is a no go to play while working. – Baarn Sep 7 '12 at 9:29
If there is a bunch of IT guys, do you think blocking will stop them? They will only be pissed off and spend the same time gaming and some more time circumventing your measures. – Baarn Sep 7 '12 at 9:37
Seems like you're on a loosing battle here JohnRoach - if the company policy doesn't discipline people taking the p*** then you're going to have a tough time; all you'll do is find a work around which will be exploited to then need to find another work around (and so the loop continues)... – Dave Sep 7 '12 at 13:26
I'm not very experienced, but could you change the networking settings to introduce a very high latency so that general internet use is fine but the lag would be too great for online gaming? – Ben Richards Sep 7 '12 at 17:18

Another option would be if you have corporate antivirus/spyware software, check to see if yours supports blocking of programs. Many of them have the ability to block common games built in.

However, it sounds like you are trying to solve the wrong problem. The problem isnt preventing people from playing games, its that they have the ability to play games on their work computers. The PCs should be locked down preventing them from installing the games in the first place.

Sadly locking down the PC's is not a viable solution as they have to have Admin rights. – JohnRoach Sep 7 '12 at 21:43

You mentioned that these are programmers and that ports needed to be opened for testing by them, so the chances are that they need full (administrator) access to their machines to do the development. Hence a technical solution is probably not possible by locking down the PCs.

Also there are so many games sites that you probably can't block all of them and, if they are decent programmers and really want to play, they can just set up a proxy relay on another machine anyway. You'v already said that port blocking isn't viable.

It comes back to the social problem of simply asking them not to do it.

Of course, if they are exceeding targets/deadlines then letting them have a bit of free time to play shouldn't be a problem.

Yes I know... Hence the reason I'm looking for a cheap way to block the online games. – JohnRoach Sep 7 '12 at 21:44
