Luzemario,
Dei uma verificada nos logs do meu fw e esse IP 218.59.238.92 tenta conexão em todos os meus ips (blocos diferentes) na porta 9064 (mesma que a sua).
Att,
Fabricio Ramirez

Pessoal,
Se fosse um DDoS viria de vários hosts. Não é comum o mesmo IP disparar requisições para tantos hosts na mesma porta. Já tive isso na porta 80, 22, 8080... parece alguém procurando um backdoor. O último IP de origem que investiguei é de uma cidade de NY. O IP muda de vez em quando, mas o padrão é o mesmo. Sempre requisições para todo o bloco na mesma porta várias vezes.
