Free powerful network and gateway server

When I started working as a network administrator, I was given a task to create a gateway to share internet connection with the users on one public IP address. I wasted around a week to figure out that how this will work on Linux machine and at that time I was not aware of anything like this but I figured it out and used NAT with iptables to configure something to use internet on a single public IP address but what if you are working now a days in small office and has been given a task to create such a server like this, Its just about a matter of few moments or hours. Let me give a list of features of ClearOS by using it you can get; I can under understand that its a long list but you can find few very interesting built-in features in ClearOS; web based interface and many other features, check them out; Its free, Open source and fully featured gateway, server and have many more rich features;
