Fiz alguns testes aqui só voltou realmente a ficar normal a rede quando desabilitei o dhcpd server do pfsense e colocar ip fixo nas máquinas .Deixando o dhcpd server habilitado e tirando qualquer cabo de rede tanto a wan ou a lan só volta a funcionar quando reinicio a máquina .Alguém já passou por isso
