Do any perticular posts in those threads pertain to this, I read both of those before making this topic.
The first thread you posted had only one post that helped. The one that said to go to
http://www.grc.com/port_6346.htm to find out if the ports are opened or closed. That told me that mine was on Stealth. Yet the rest of the topic fails to explain how I can get around this.
The second topic: I followed those directions to the T. Several times. Each time they had absolutely no effect.
