Opa Otacílio,

Mas você acha que pode ser a minha em1 ou a outra ponta que está ligada 
num concentrador PPPoE?

Porque está assim:

PPPoE Server<---> em1(Firewall)em0 <---> Internet

Será que é a interface de rede do PPPoE server que está com problemas e 
gerando esse storm ou a minha própria em1 no FreeBSD. Porque estou 
inclinado à interface do PPPoE Server.
