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! Jack On Sat, 26 Jan 2002, Reginald R.
