I have always had an open NAT. I just recently moved to a new state. Had to get a new modem and everything through Time Warner Cable. So my NAT is now moderate. I thought it may be a router issue but I checked all the common steps and it seems fine. uPnP is enabled and all that. I ran a direct connection (straight from my modem to my Xbox One) and the NAT still shows moderate. What can I do about this? If I call TWC will they be able to help me? Perhaps a new modem or a different type of modem?
I haven't done port forwarding on my router just FYI. I suppose I can do that if you guys think it would help.
Router = Netgear N600 Wireless Dual Band Router (WNDR3400v3)
Modem = **** DG860
Thanks for the help and advice.
