Wireguard and ovh anti ddos problem

[MisterGranti67]

Hello, I explain my problem, I have a tunnel through my home server and a ovh vps, everything works perfectly, but the problem comes from when I ddos the vps on the forwarded port, the antiddos works and migrate but blocks all new user wanting to connect to the forwarded ip/ports because the anti ddos thinks that they are booting with wireguard but not, so wireguard trigger the migration when there is a ddos attack, so I don't know if anyone had this problem and if someone have a fix but I would like some help thanks
