If you are using iptables try <iptables -L -n -v .
This will indicate which rule or policy got the packet and hopefully
what happened to it.
Remember for iptables forwarded packets don't transverse the INPUT or
OUTPUT rules.
Send back the info to me I'll look at it if you can't see what is
happening.
