Protocol 8864 BURST 200Mbp/s - BUG? v6.43 CCR1036

Good day.
recently I deactivated a server in which I used a public IP / 30.
When removing the Queue I had a + 200mbps burst in which I would not stop.
I activated Queue again so that consumption would not be high.
I noticed that this problem is in this public IP,
I verified the settings and not anything of them in my network. and as if the 8864 requests came out through my WAN port.
Another solution was to activate these 4 IPs in loopback interface.
I tried to give TORCH to see where this whole UPLOAD is going, nothing appears besides Protocol 8864.
I noticed that on the internet there are quite a lot of people who have gone through this. Can you help me?

Note: I deactivated pppoe server on this ethernet 4
