[FUG-BR] IPFW

[Márcio Luciano Donada]

Pessoal,
Uso faz um bom tempo já o IPFW, mas hoje tive uma surpresa ao compilar
ele, no kernel adicionei as seguintes regras:


options         IPFIREWALL
options         IPFIREWALL_VERBOSE
options         IPFIREWALL_FORWARD
options         IPFIREWALL_NAT

E ao compilar o kernel o seguinte erro:

Alguém faz idéia do que estou fazendo errado.
