How To Block Fortnite

I've got someone asking me to block the game Fortnite at their office.  The trouble is that it appears to be hosted in AWS and the servers are dynamic.  Anyone run into this or have any suggestions on how to do it?

Heh... check this out. I did this for our school, Fortnite will load, but with ping times of well over 1000ms its mostly useless! To find this information, i loaded up the game on a work computer and did a wireshark capture, from there i made this rule. Works wonders!2018-04-27 08_47_35-Traffic Shaping - Meraki Dashboard.png

Find out who is playing the game at work and for how long, then deduct that time from their paycheck. If they can still complete their work, then they are being efficient and your company will save money by only paying them for the time they worked.  They can be rewarded for their efficiency by using their leftover time to either complete more work for more pay, or have unpaid time to play games. If they don't complete their work, then you can replace them with someone else who would rather get paid then play games.  I think allowing people to be responsible for themselves as much as possible is the best method for cases like this.  Otherwise, you will always be playing whack-a-mole with every new time-wasting app/game/site.  This also forces managers to pay attention to their employees, instead of relying on the I.T. police while they play games too ;-)

Not disagreeing at all.  But I'm an IT consultant and it's not my place to do that for them!  They asked more for something specific and it's my job to deliver it.

Kind of a big deal

You could use a layer 3 firewall rule and block the FQDN and ports give in the traffic shapping example.

 

You could probably also use content filtering and block "Gaming",

Yeah - that's what I wanted to do.  I just can't find any documentation online of what ports or destinations fortnite can be found at.

Re: How To Block Fortnite

Here is what I would do.  Start with the gaming device off.  Start a packet capture of all DNS queries.  Start up the gaming device, and then the game.  Stop the packet capture.

 

Now you have a list of the DNS names it needs to work.  Chances are one of them is used to login or verify that the game is legal and legit.  There is possible one or more domains used to start the actual game as well.

 

Now that you have these, create a firewall rule blocking these domain names using FQDN rules.

I'm thinking you'll be finished the whole job in 15 minutes.

According to the Epic Games web site the ports 80, 433 and 5220 are the ports uses, so that may be a little awkward.

 

However they state that epicgames.com must be accessible to play, so I guess a layer 7 rule for that domain would be a good place to start.
