PCC (wiki da mikrotik) não funciona com interfaces dinâmicas

Peguei o exemplo do PCC do wiki da Mikrotik e como tenho 4 interfaces com IP dinâmico fiz a adaptação abaixo.

Ele aceitou mas só consigo acessar as redes diretamente localizadas (que seja na LAN quer seja nas WANs). Para testar coloquei um cabo na minha máquina na LAN do RB750G e dois cabos da WAN ligados a um servidor de DHCP.

Eu desliguei o add default route das interfaces que pegam IP dinâmico. E retirei as portas 3,4 e 5 do slave da porta 2.
