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.
