match by originator interface

[Rob Collins]

iptables -A FORWARD -i eth1 -m state \
   --state ESTABLISHED,RELATED
will match incoming packets who are already a part of
an established connection.  So, if your rules further
only allow '-i eth0 -m state --state NEW' to go
through, and your rules do not allow the firewall
itself to originate outbound connections, the rule
fits your requirements.

Is there any way i can write a rule to match a packet
on interface
eth1 only if it belongs to a connection that was
originates through 
interface
eth0?
