ipfw2 question

[dnr]

hello,
i'm solving such a problem:
router with 3 eth i-faces:

em0(vlan10)
                    (vlan1000)fxp0
em1(vlan11)

I need to split traffic into two pipes
pipe1 from vlan10 to vlan1000
pipe2 from vlan11 to vlan1000

fxp side supplys traffic to many different subnets
em0 is trunk to the world networks
em1 is trunk to the national networks
so I cannot write these rules in IP level....

doing it in the following way doesn't works...
ipfw add pipe1 pass all from any to any via vlan10 in recv vlan1000
ipfw add pipe1 pass all from any to any via vlan10 out xmit vlan1000
