Port forwarding help

[Jackestrel]

Hi, I am very new to Linus Tech Tips

I made an account just to get help with Port Forwarding

I have been having trouble port forwarding on my room Desktop.

 

Things I have:

PC: Windows

Modem: arris tg862g/ct

Router: Netgear R6100

The arris tg I have is a router/modem combo but I only use it as a Modem. The Router is connected to the Modem by Ethernet.

The network is not in Bridge mode

 

Things I have tried to do for Port Forwarding:

I gave my router and my computer a static IP

I have made a made a port forward rule on the router 

I have Port forwarded my router through my modem ( and enabled port forwarding through the modem)

I made an Inbound and Outbound rule for my Windows Firewall for the port

I have checked that the ISP does not block the port I am attempting to open (443)

I have also tried to download Port Forwarding software but that still failed to help open ports

 

I have done all of the things above but when I go to any port checker, my port is still closed. 

Is there anything I am missing in these steps?

-Thanks for your time

Put the modem into bridge mode so that you can let your Netgear router do NATing.
