The man page is not very clear to me on howto do POSTROUTING of port to some internal machines. What I am trying to do is port forward 2090 to some of my intranet machines. Man page says this
DNAT
--to-destination ipaddr[-ipaddr][
ort-port
could someone be able to show me the correct way to write
this. This is what I have and it works for one machine only.
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 2090 -j DNAT --to-destination 192.168.1.2:2090
man page says this, but I recieved an error about the first ip.
iptables -t nat -A POSTROUTING -i eth0 -p tcp --dport 2090 -j DNAT --to-destination 192.168.1.2 -192.168.1.3:2090
I tried this and it has no errors but it don't work.
iptables -t nat -A POSTROUTING -i eth0 -p tcp --dport 2090 -j DNAT --to-destination 192.168.1.2-192.168.1.3:2090
help will be !!!
