This is probably a stupid guestion but when you are opening and closing ports (through the Tomato GUI) and adding various rules for blocking users/ports/addresses, etc....does Tomato manually create all these aforementioned rules in the background using the iptables command? If so, where/how can you view these settings/changes? I was wanting to see how they are setup/changed so as to learn a little more about the iptables command line. I am new to Linux, and I am reading up on iptables, and was trying to get a real-life example/understanding of how it works. Great Forum! Thanks.
