Hello All,
When I'm trying to do something like this:
iptables -t nat -I POSTROUTING -p tcp --dport 8080 -j DNAT --to :80
I get: "iptables: Invalid argument".
What I want is only to translate destination port of all TCP-packets
going to some_ip:8080 into some_ip:80. I don't want to change IP. It
seems that syntax of this command is corrent, but... What is wrong?
Thanks!
P.S.: Kernel 2.4.31, iptables v1.3.2
If you want to do that you should read the
iptables-tutorial.frozentux.net, then use the REDIRECT target:
iptables -t nat -A PREROUTING -p tcp --dport 8080 -j REDIRECT --to 80
