How to determine where DDOS is in LAN?

Question

Computer networks

Good afternoon,
There is a local network for 30 computers, the Keenetic Extra II router is used as a gateway. Last month, the provider began to call and warn that a DDOS attack was periodically going on from our ip. The provider gives data on the attack time and that's it.
I checked computers on the local network for viruses with CureIT, but this did not solve the problem.
Is there any way to trace the router logs from which specific device the attack was made from?

I remember - I'll knock additionally
ps I don't remember how.. (although I was a fan of the product when I was "in big" .. (( .. to replace
