Trouble port forwarding w/ router and cable model
I'm attempting to port forward so that computers on other networks can access my Minecraft server - I've gone through the guides and I believe I've followed all the steps correctly for port forwarding on my Netgear R6120 router, and I've created the necessary permissions on my computer's firewall, but I'm still not able to see the port on https://canyouseeme.org/. It seems like the problem might be coming from my Netgear CM500 cable modem. I have a cable and an ethernet plug coming out of my wall - the ethernet goes into the router, and the cable goes into the modem. Is this setup going to get in the way of my port forwarding? I've seen suggestions to change my modem's settings using the interface at http://192.168.100.1/ but the only options there pertain to the frequencies of the cable connection and resets. Is it even possible to port forward with this router/modem setup? Is there any other information I can provide for a more helpful/specific response?

If you haven't tried it already, you find find a few useful tips here:

I have a cable and an ethernet plug coming out of my wall - the ethernet goes into the router, and the cable goes into the modem.I don't know what the "ethernet plug coming out of my wall" connects to. The usual string of device is:
- connection to Internet service provide (outside workd)
- modem (CM500)
- router (R6120)
- your network
The usual default access to the router is through 192.168.1.1
By the way, don't expect much of the R6120. It is one of Netgear's bottom-of-the-range routers. According to Netgear's manual for this device, not always the most reliable source of information, the LAN and WAN ports support only 10BASE-T or 100BASE-TX. That makes it slower than many newer internet services and most modern network hardware, including your modem.
This may not matter to you, but be warned that it will hobble you if you ever sign up for faster Internet, anything faster than 100 Mbps is a waste of your money.
It also slows down whatever is going on in your local network. Newer devices support at least 1000BASE-TX.Thanks for the advice about my router, I know it's cheap (I'm a grad student lol). I checked through that search list you linked and didn't see anyone else with my specific problem. I've gone into the router settings at www.routerlogin.net, added a static IP address to the computer running the server (192.168.1.14), added the port forwarding service for 25565 TCP/UDP on my router, and allowed the traffic through my computer's firewall, but external traffic still seems to be blocked. Interestingly enough, the IP displayed in ADVANCED > Internet Port > IP Address is the same as my external IP, so I don't think my modem is acting as a second router here, despite the fact that it seems to be blocking service in the same way a second router that wasn't port forwarded would.
To be clear, 192.168.100.1 isn't the address for my router, but for my modem. Is there anything I might have looked over?

I know. In this context it is a red herring.
The fact that you mentioned it suggested to me that you didn't really understanding what was going on.

Who knows? You didn't respond to my questions about the layout of you network.
For example, I said:
"I don't know what the "ethernet plug coming out of my wall" connects to."
What is it? What does it connect to?
