What version of FreeBSD are you running?  You shouldn't even be able to
do this in recent versions (if you have multiple addresses on the same
network, all but one of them should have a netmask of 255.255.255.255).
This isn't the way to accomplish what you seem to want anyway.  The best
way would probably be to use if_bridge in 6.0.  Alternativly, you may be
able to assign an address to one and bridge the two of them together.
