FreeBSD doesn't want you to put multiple NICs on the same subnet, modulo the following section from "man bridge": By putting both physical and logical (vlanX) interfaces in the same clus- ter, a FreeBSD box can also implement what in commercial terms is called a "trunk" interface. This means packets coming from one of the interfaces in the cluster, will appear on the wire on the "parent" interfaces of any vlan interface belonging to the cluster, with the proper VLAN tag. Simi- larly, packets coming from a parent interface, will have the VLAN tag stripped and will be forwarded to other interfaces on the same cluster. See the EXAMPLES section for more details. Do you want to do trunking for extra bandwidth, for redundancy in case of failure...what problem are you trying to solve? -- -Chuck
