CM1200 Ethernet port not working

[woody3077]

On my Nighthawk CM1200 the only port that works is the top port. Is this a issue with my modem or are they turned off?

Thats how they function. Because its a modem only device and not a modem/router combo device.

most isp's only allow 1 public ip address. (cox/xfinity/spectrum/+ others)

Certain situations allow more IP addresses assigned like if you're on a business class line, if you pay for extra IP addresses, or if you're isp is one of the lucky few who allow more than 1 public ip address.
