Unknown connections when school is out and no one is in

Miata · ‎10-27-2015

Currently the school is out due to holidays, but I can still see connections being active.

Can someone confirm that these may just be devices idling that are still connected to the Internet.

Kind regards

Seams to me like DNS traffic (UPD 53)?

So this is nothing to worry about, because it's just usual traffic? Please elaborate a little bit.

Thanks

Well, I can't say it's usual, because I don't know your system. :) If you have some servers or computers turned on all the time and connected to the Internet, than I would say it's fairly normal for them to use the network (OS/software updates, services etc).

Sometimes, FortiGate itself can use UDP 53 for FortiGuard updates, if the usual port is not functioning for some reason.

Thanks for your replies.

Yes the computers are constantly on, so that would make sense.

It's only small amount of data being generated too, so there's nothing too strenuous which backs up your point of them finding updates etc.

Is there anything I can do to clarify this on or off the Fortigate?
