I cannot get video or audio working on the program "net meeting" I am currently using the D-link router, comcast cable internet and windows XP. People have told me to activate port-forwarding but I do not know how. They feel that I cannot get audio/video because of my rotating IP address. I have absolutely no idea. I am a basic at all of this and require this connection for my master's program at UT. Help. I am lost and don't know where to go.
