  1. Why do you want to do this? It seems like a fundamentally bad idea. It would go against every known standard of expected operation that exists.

    That said, you could do this using the PREROUTING chain in iptables. These rules will work for the following assumptions:

    • eth0 is your public interface
    • You only need TCP redirected
    • Your public IP address is 192.1.1.1
    • You only want to redirect ports 1 through 65535

    Rule:

    iptables -t nat -A PREROUTING -i eth0 -p tcp --dst 192.1.1.1 --dport 1:65535 -j REDIRECT --to-port 80
