I've had this problem for a LONG time now, I've been searching through google and other search engines and clicking on the matches that are related to my problem to find a straight forward answer that actually works... I have no firewalls blocking the port and application that is using the port and my UPnP and Extended Security have both been disabled.
Telecom has a very complicated port configure page that half the time doesnt even apply to the computer I want it to... I use a SpeedTouch Thomson ST5x6v6 and I currently have only used it on two computers (I removed the computer that I dont use from the Home Network list). Just a simple dream to create a server on a game, turned into a nightmare trying to create it... and if you really want to know, im trying to use port 25565
