   If you use the Linux ethernet bridge facility the IP address is allocated
to the bridge regardless of the number of ethernet cards specified as part
of the bridge, each of which is set to promiscuous mode. It is designed to
work as an invisible bridge, with packet filtering firewall rules added
specifying interfaces as eth0, eth1, etc. INPUT access to the box itself can
be restricted by these rules. Other ethernet cards can be used independantly
or as parts of other bridges.
