Hello,
I need to port forward all traffic locally going to port 80 to port 
8040.  For the external interface eth0 this works, I thought it would 
work for the internal/loopback as well. Nothing else is turned on
, all other settings are open.

/sbin/iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT 
--to-port 8040

this doesn't work for the internal network, 127.0.0.1 lo, not sure why
System info: Redhat7.3, 2.4.20 kernel, iptables-1.2.8-8.72.3
Thanks
