CGNAT OR NOT? WHY CANT I PORT-FORWARD

Hello. Given the customization you are attempting to accomplish, it may be best to utilize your own purchased router or WiFi modem, or enable Bridge mode on the Gateway and use your router. You do not have to rent a Cox Panoramic Gateway, and a list of approved modems and WiFi modems are here www.cox.com/residential/support/cox-certified-cable-modems.html. If you choose to utilize your own modem that's among the list on cox.com, then you can return the Gateway to a Cox retail store. The Gateway can be placed in bridge mode if you have a router you would rather utilize for customization. https://www.cox.com/residential/support/enabling-bridge-mode-on-the-panoramic-wifi-gateway.html.
