Can't port forward

Hello, for the past year or so I've been trying to port forward the port 25565 to host a dedicated Minecraft server for me and my friends. I was always able to join with my local ipv4 address but my friends couldn't join with my public IP. I never got it to work and gave up after following all the steps I could find in forums with people having the same problem as I was. Recently I've tried to host a dedicated Terraria server instead (port 7777), but same problem there, the port just does not want to open.

I've used several port checker websites and the PortForward software from https://portforward.com/ but it always says the port is closed.

I think it's worth mentioning that I had no problem whatsoever port forwarding the port 25565 with my last router. It was an ASUS Router, which I can't remember the name of.

I would be forever thankful if anyone could help me solve this issue, please ask me for more information/specifications if it is needed.

Router: NETGEAR R6220, Router Firmware Version V1.1.0.86_1.0.1

   That's an argument between you and your ISP. If you have Internet
access, then that's not the problem.

   But, while we're looking at that picture...

   BASIC > Internet : Internet IP Address : IP Address (as shown in your
picture) provides the same critical fact: 100.68.<blur>.<blur>. Plug
that address into the form at: https://whois.arin.net/ .

   As you can see, that's not a public IP address. My guess would be
that your ISP is using carrier-grade NAT, and that's defeating your
attempts at port forwarding.

   The only solutions I know are: 1) to ask your ISP for a real public
address (for which they might charge more), or 2) to use a tunneling
service like the one mentioned in another thread (near the end):

Some ISPs do not permit servers for residential customers, but I'm
confident that they'll tell you that if you ask.
