Trevor,

You may be correct but I believe it can be managed by using the IP
addresses

-A INPUT -s ###.###.###.250 -i lo -j ACCEPT
-A INPUT -s ###.###.###.251 -i lo -j ACCEPT


-A OUTPUT -s ###.###.###.250 -j ACCEPT                
-A OUTPUT -s ###.###.###.251 -j ACCEPT

where ###.###.###.250 is addressed in eth0
and   ###.###.###.251 is addressed in eth0:1   

This is how I was able to do it.
