Now it make sense.  In this case, you do not need an IP per interface,
rather you can make the 4501 behave as a software switch - the 3rd
option I noted.  Since this has nothing to do with Soekris and will
depend heavily on what flavor of Linux you're running, this isn't
really appropriate for the list, but the following is a brief synopsis
of what you need:

 - the 'bridge' kernel module
 - brctl from the bridge-utils project (http://bridge.sourceforge.net/)
 - Create a bridge (brctl addbr)
 - Add interfaces to the bridge (brctl addif)
 - Optionally configure your bridge with an IP (ifconfig $bridge 192.168.0.1)
