Panoramic Port Forwarding
All the posts I see about this being resolved are 10-11 months old, and walk you through an option that doesn't seem to exist any longer. eg: https://forums.cox.com/forum_home/internet_forum/f/intern...

Probably not advice you want to hear right now but... dump the Panoramic modem (why pay rental fee?) and purchase your own cable modem/WiFi router combo or separate cable modem and WiFI router devices. Purchasing your own equipment will pay for itself within the first year or two. With your own WiFi router, you'll have more network configuration options. I've got the Arris SB8200 cable modem and Gryphon mesh router system.
