Hello!  I would like to have the following setup, in order to implement
load balancing:

[ internal net ] --(100M)-- FreeBSD Box -+--(10M)---CM 1  - [ internet ]
                                         `--(10M)---CM 2  - [ internet ]

CM1 and CM2 are two cable modems, connected to the same cable modem
network.  I would like to communicate to some host that is outside the
cable address space through both interfaces.

Suppose my two addresses are 123.123.123.2 and 123.123.123.3, and the
gateway should be 123.123.123.1.  I would get lots of "arp:
123.123.123.1 is on ed0 but got reply from ed1" messages, and I think
there might be a conflict between the two interfaces, which would have
to be configured in the same /24 net (in this example, 123.123.123.0/24)

Any ideas how to solve this?

Thank you
	Alex
