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 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?
From the man page it looks like you need a colon on the port for DNAT
(and no IP
as it will stay the same if not specified, just what you want).
iptables -t nat -A PREROUTING -p tcp --dport 390 -j DNAT
--to-destination :5432
I haven't tested, but it seems it should work.
Yes, removing the IP address was probably an improvemnet, but not
enough to make it work.
