[GTER] Portas 445, 135, 137...

Tue Jan 26 10:31:54 -02 2010

Prezados,

	Não seria útil se os provedores começassem a bloquear essas portas  
para evitar a disseminação de vírus, trojans, etc ??

	Os serviços nestas portas foram feitos para utilização em LAN e não  
em WAN.

	O volume de pacotes é enorme e consome muitos recursos de banda,  
hardware e pessoal.

	Aqui filtro esses pacotes a anos e nunca tive uma solicitação para  
liberar essas portas.

	Só um exemplo do meu filtro, o volume é enorme :
