The problem was with the Hitron CGNM-2250-SDL modem/router. My ISP (Suddenlink) does not allow modification of modem settings, even through the DMZ setting. I purchased a Netgear C3000 modem/router and had the Tech Rep from Suddenlink activate it in their system. I now have an OPEN NAT setting on all my games. Thanks for all your help FalconR6
