[FUG-BR] Mirror Traffic Vlan FreeBSD

[William Nascimento]

Caro,

Tenho algumas vlans e gostaria de fazer um MIRROR do tráfego de uma vlan específica para algum outro host.
Alguém já fez isso ? Será que com IPFW ou PF é possível ?

Eu sei que posso fazer no switch ou usar uma interface em modo bridge no FreBSD ( não é o caso aqui ).
