Default Iptables rules for eth0 and eth0:1

Can I specify in-interface and out-interface for virtual interfaces
(configured eth0 and eth0:1)? Or in other words, is it possible in
iptables to set rules as iptables -i eth0 -o eth0:1
(Does it differentiate between eth0 and eth0:1?)

I don't think that is possible. You could specify
-i eth0 -o eth0 and specify the source and destination
IP ranges as well.
