I have a strange problem I can't seem to Google help on, so thought I'd try here. Basically, I can get my PC's (Win10) NAT to be Open, but then after a few days it goes back to moderate. This is with a Cisco DPC3848V set to upnp and dynamic dhcp assigned IP Address.
The strange part is, if I disable and re-enable my ethernet port, then my NAT goes back to open - every time.
It doesn't take long to do that. But I was hoping to find some way of maintaining an open NAT. I have no clue what is causing it to flip back to moderate.
Any help would be appreciated. Thanks!
