I'm using my linux box as a router and I have an application that is make all the request in port 95.
I need to make an iptables rule that will change the original port of any destination ip addres to 80.
I know how to do it for a specific destination ip but I could not find the way to do it for any destination ip.
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 95 -j DNAT --to 188.8.131.52:80
184.108.40.206 is the Google ip, but I need the rule to work for any ip. Something like:
iptables -t nat -A PREROUTING -i eth0 -p tcp -d ANY --dport 95 -j DNAT --to ANY:80
I know that it is possible to do in checkpoint firewall but it is a little expensive...
