"Cascaded"?  You mean they're actually hooked up to each other?  That
would be a mistake.

Any given address should only be coming in on one interface.  You
should fix your configuration so that doesn't happen.  Either make
sure that the two networks are separate, physically and in IP address
space, or else get rid of the second NIC, and arrange things so you
only have one network.
