Simple Port Forwarding works with WebPages and not directly with your router. No different than using Firefox, IE or any other browser to setup port forwarding yourself. The program works by automating the process for you. So whether you don't understand how to forward ports, or you're simply looking for an easier way to forward ports then this program is for you. The main interface of the program is small and clean. Giving options of seeing what is going to be forwarded to the router and how many entries and ports it will use in the process. You have the ability to save your list and send it to another user of the program. An example would be, lets say you have a family member who lives far from you and doesn't really understand port forwarding, so instead of spending a lot of time over the phone walking them through it you can simply have them use the program and have them load the list and update their router, then your all done. Now that's a time saver.
