Below is rockstar23 solution to yellow light on listening port, which worked for me. All others did not.
HEY EVERYBODY..I HAD THE SAME PROBLEM BUT I FOUND A WAY TO OPEN THE PORT & NOW I HAVE GREEN DOT..... TO FIX GO : OPTIONS > CONNECTION > AND CHECK THE BOX SAYING : REMOVE PORT ON NAT/FIREWALL WHEN EXISTING ( WINDOWS XP ONLY )
