For various reasons I would like to forward trafic to port 390 to
port 5432 on the same host. One would think this would be a
simple task for iptables but I have now tinkered with this for two
days, and I still fail to get it right.
I try something like:
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A PREROUTING -p tcp --dport 390 -j REDIRECT
--to-ports 5432
I have also tried :
iptables -t nat -A PREROUTING -p tcp --dport 390 -j DNAT --to
192.168.0.5:5432
where 192.168.0.5 is the address of the host
Any ideas on how to do this?

Hi,
add:
iptables -A FORWARD -p tcp --dport 390 -d 192.168.0.5 -j ACCEPT
Thanks., but unfortunately that isn't enough to make it work.
Is there any special kernel modules or /proc/sys/ipv4/* settings I need
to do,
or could the problem be that it is the same host?
