You seem to be forwarding pings to different interfaces per script invocation (usually during boot time)? What are you trying to accomplish? If you state your goal, the list might be able to come up with a solution using iptables. Other things: Usually if you accept pings in one direction (say -i eth0 -o eth1) you want pongs to go in the other direction (-i eth1 -o eth0). I'm not exactly sure why you are forwarding from an interface to itself, though I don't have much experience with this kind of thing.
