Been there done that :-) Make sure you have proper tc rules for _both_
directions, and try tcpdump on all three boxes. Not sure if you already
knew this, but tcpdump has a ton of command line options to make it just
show the packets you're looking for. Also double-check your NAT and the
routing on box 1 and 2. I suspect something like this is happening to
you:

z.z.z.z:1024 SYN -> box3 -> box1(NATSRC=x.x.x.x:4001) -> a.a.a.a:80

z.z.z.z:1024        box3 <ACK loops back to> box1     <- a.a.a.a:80

So on each box get two consoles (one for eth0 and one for eth1), then do
a:
tcpdump -i eth[0|1] -n port 80 and host 66.1.155.123

and then go to your client workstation and browse to
www.monkeynoodle.org. The tcpdump output should make it very clear what
happened.

Good luck!
