I'm in a CGNAT?
Hello! I'm trying to open the 25565 port but is being a nightmare. I allowed traffic in the firewall using PoweShell
New-NetFirewallRule -DisplayName "Minecraft Server" -Direction Inbound -LocalPort 25565 -Protocol TCP -Action Allow
New-NetFirewallRule -DisplayName "Minecraft Server" -Direction Inbound -LocalPort 25565 -Protocol UDP -Action Allow
New-NetFirewallRule -DisplayName "Minecraft Server" -Direction Outbound -LocalPort 25565 -Protocol TCP -Action Allow
New-NetFirewallRule -DisplayName "Minecraft Server" -Direction Outbound -LocalPort 25565 -Protocol UDP -Action Allow
And did the Port Forwarding. Still, when I check it at https://www.portchecktool.com (whit the server running) I get "Connection refused" I learn hours later and thanks to this server that some ISP uses CGNAT but I don't know if I'm the range of one.
WAN IP: 100.127.0.0/17
I did something wrong on the Port Forwarding/Firewall or I have to call my ISP?

We may have bad news for you :C
Open your router's configuration interface. Somewhere you'll see something like 'external' or 'public' IP.
If your external IP is in one of the following ranges, you're basically screwed as long as portforwards go:
- 10.0.0.0/8
- 172.16.0.0/20
- 192.168.0.0/16
- 100.64.0.0/10
- any IPv6 address/range - This shouldn't be a problem, but Minecraft's IPv6 support is still rather quirky. You're at your own but we're happy if you share your experience.
You should ask your ISP for a public and IPv4 address (but this may cost you money).
NB: your internal IP should and most probably will be in one of the first three ranges, don't mix them up

is in the range of 100.64.0.0/10?
