If you have multiple NICs in the same Ethernet broadcast segment then I 
would recommend you to enable "arp_ignore".

    echo 1 >/proc/sys/net/ipv4/conf/all/arp_ignore

If not things will get very confusing with traffic "randomly" coming in on 
either interface.

Once this is done you can firewall each NIC separately as you please, 
policy routing, marking etc to control how the interfaces are used.
