Hello netfilter! I am a newer for Linux OS. I made use of "NAT" Service under MS Windows Platform to realize internet sharing before. Since I met Linux OS, I found that Linux is a greater than MS Windows.So I make a decision, that is to realize internet sharing under Linux with "iptables",who can tell me the command or script.
