How to enable port forwarding?

None of those are the port I need to enable forwarding for. How do I enable port forwarding so I can play an online videogame? I attempted to use the chat on the website, but all they did was try and upsell me on new routers and attempt to send a technician out, for which I would have to pay.

Are you having any trouble with other sections of the app? What about other options in Advanced Settings?  I've had my peers check the app and aren't seeing any issues with the WiFi app. If logging out, clearing app cache and logging back in doesn't clear up your ability to access the port forwarding options in the app please email us at cox.help@cox.com with your full name, complete street address, description of the trouble you're having and a link to your thread. 

I download the app exclusively to enable port forwarding after being prompted to do so when attempting to do so by accessing the router via web browser through my local network.

Under Advanced Settings, there are 4 options. The top option, DMZ, and the bottom option, Port forwarding, both result in a "Something unexpected happened. We can't display your details right now. Please try again or come back later." with a button that says "Try again", that brings me back a page, and it does this every time.

The other two options, DNS server and LAN & WAN, both appear to function properly.

I have tried logging out, deleting cached data, and logging in, to no avail. I will email now.

What modem are you using? What cell phone/tablet are you using the app on?

I'm having the very same options, was told to use the app, now that i have the app I keep getting the "Something unexpected happened." error, nothing i have done has fixed the issue and even with trying to "chat" it keeps going nowhere and keeps getting told that the app should work.
