Linux Protection against DDoS

[Zenoh]

Hello guys, thats my first post here and I need help from more experienced people.
I'm an administrator and developer of an otserver and and I'm getting several ddos attacks.
The biggest attack was 204 Gbps and I'm having troubles to protect my server.

What solution to solve this problem do you recommend to me?
I already use a hardware antiddos protection.
