Thank you SD
Sorry for the "slight" delay in answering you. Life caught up with me and certain things were put on the far back burner. Another issue popped up reminding me of this thread I posted.
Thank you Saab Dastard for your advice. I have changed the port numbers, simple yet effective method!
I have since upgraded to a UI dream machine that manages port forwarding, but the issue still prevails. I am basically trying to remotely access a Denon streaming device, which I am able to under my local IP, but not remotely.
