[GTER] PPPoE NE20

[Juliano GigaNET]

Bom dia, estou precisando de um help de voces.

Estou montando meu concentrador PPPoE em um NE20e-s2f e estou com um 
problema que me impede colocar em producao. O PPPoE conecta 
perfeitamente .. navega por alguns instantes e depois o pppoe é 
desconectado .. Depois de alguns segundos ele reconecta e assim fica o loop.

Oque poderia ser? Alguem ja passou por este cenario / problema?

Detalho abaixo minhas configuracoes atuais:
