LARTC - May 2006 - How to match 2 networks using 2 ethernet cards sharing bandwidght?

Hello all,

    I have this situation:

eth0 - internet backbone

eth1 - network 192.168.0.0/24 (clients)
eth2 - network 192.168.1.0/24 (clients)

    My problem is that this two networks, one into each interface, need 
to share 256 Kbps. I could not make a way to shape this both networks 
becouse they are in different interfaces. Anyone knows some way to make 
it happen?

Att,

Nataniel Klug
