I went and bought the program cause it is an easy tool to optimize your online connection in video games and such. At first it didn't work for me but the tech support guy helped me find a solution when i basically gave up. He helped me optimize my two routers so that i can open any port that i need. He was kind and knew his way around the routers/modems. I suggest this program to anyone trying to open his port cause it is easy to get around the program and if you don't know how to, you get the support you need from the developer.
