under attack Ddos

Hello to everyone,
I have a mikrotik cloudcore and behind this mikrotik I have a server.
In the mikrotik I have a open port to the server, so I am receiving attack with too many IPs per second to the server with empty packets, is there any rule in ip firewall filter to cut or drop that? please help me. Thank you
