iiuc, you have the following types of packets on eth0:

	x.x.x.x/24
	y.y.y.y/24
	z.z.z.z/24
	vlan2:a.a.a.a/24
	vlan3:b.b.b.b/24

So, you need x.x.x.x/24, y.y.y.y/24, and z.z.z.z/24 to get routed into
vlan3.  Does traffic need to go the other way?  Is there broadcast or
multicast traffic to worry about?

thx,

Jason.
