I need to speak to an agent to check something but there is no way to open a live chat. I can't even speak to Oliver. https://www.cox.com/residential/contactus.htmlIs the button for live chat missing for anyone else?

Your internal IP isn't private, only your external IP. As long as it's in the same DHCP range as the router, it doesn't matter. Also, make sure to set a DHCP reservation for that IP address to the MAC address to your PC's NIC.
I would suggest trying bridge mode between the modem/router and your PC. ADVANCED > Administration > Router Mode and set to no. You may have to reboot the modem/router and PC after as this will assign a new external IP address.
I'm not seeing a router mode in the settings.
It may have been removed at the firmware level. That is unfortunate. You could test the router's firewall by assigning your PC to the DMZ. The DMZ option should be available at ADVANCED > Setup > WAN Setup. This would only be a temp. work around for testing as leaving your PC IP in the DMZ is a security risk.
Assigning my PC to the DMZ has fixed all my issues but the security issue is worrying. Is there anywhere to go from here?
There is a couple things you could do. You can contact Netgear and ask them why port forwarding isn't bypassing the devices firewall. This won't fix the problem but it will report it and perhaps help others. I would start at the Netgear forum found below.
If you would rather go nuclear on the issue, you could buy a new modem and stand alone router. If you want suggestions on what to buy, just ask.
