Firewall won't let normal traffic pass

  • I got a little problem.
    I am running my own gameserver and since I started getting DDoS attacks I switched to a Pf Sense firewall.
    It's blocking every attack and still let's pass normal traffic to the gameserver and website.
    But there is a certain attack, a udp attack, that it is blocking but when it does it will block normal traffic too.
    Even when it is just a attack of 25mbits or higher it will block both.
    I do have the source of the attack I don't know if it will help.
    Is there any possibility to let it block the attack and still let normal traffic pass?
    The source is in the attachment.
    It's a source of a shell.
    Thanks for reading this and hopefully someone could help me.
    Sorry if this isn't the right place to post it just tell me and I will remove it.
    And sorry if there isn't anything clear my native language isn't English.

  • So there is really no one that could help me?

    Throughput in Mbit/s is meaningless for a DoS of that type. You are worried with pps (packets per second).

    Tiny packets, especially tiny UDP packets, can be quite troublesome to forward in large quantities.

    Some tweaks here can help:
