Port forwarding

Hello!

I have been trying to portforward the port 25565 for the purpose of opening a minecraft server for the past year. I have finally decided to open my own thread in hopes of some help.

 

What I have already tried:

Portforward on my router

Disable firewall in windows

Allow ports through firewall

Disable anti virus

Disable windows defender

 

The server works on LAN

I have made sure to use the right ivp4

My friend has my public ip

Multiple people have tried

Others can join in LAN

Model: R8000P|Nighthawk X6S AC4000 Tri Band WiFi Router

   Is that accurate?  Firmware version?

 

> Portforward on my router

 

   Actual port-forwarding rule(s)?  Copy+paste is your friend.

 

> The server works on LAN

 

   When you do what?  Do you mean using the LAN IP address of the
server?  What happens if you use the WAN/Internet IP address of the
router?  Does the IP address of the WAN/Internet interface on the router
match your public IP address?

 

> I have made sure to use the right ivp4

 

   I don't know what that means.  What does "the right ivp4" mean to
you?  "use" for what?


> Multiple people have tried

 

   "tried" what?

Re: Port forwarding

Dont know how to do that thing you do in the chat but I will try to answer your questions

 

That is the exakt model

 

Yes I have an actual portforward set up in the router

When i launch the server on my computer and someone joins using Lan (the computers ipv4). When i use the ip of the router it works on LAN but not for others (100.67.xx.xxx). Im not sure how to check if they match. 100.67.xx.xxx is the ip of the router and 83.233.xxx.xxx is the ip of the computer.

 

I mean that I have used the ipv4 of the computer to run the server, portforward and try to join via LAN.

 

Multiple people have tried joining the server on their own computers using my public ip (83.233.xxx.xxx)

   Which is it, your public IP address, or the address "of the
computer"?  Which "the computer"?  How/where did you find that address?
(Looks to me like a Bredband2[.se] public address.)

   That tells you that the router is doing port forwarding properly.

 

> [...] 100.67.xx.xxx [...]

 

> Im not sure how to check if they match.

 

   Does "83.233.xxx.xxx" look to you like "100.67.xx.xxx"?

 

   Plug that "100.67.xx.xxx" address into the form at
"https://whois.arin.net/", and get discouraged.

 

   Apparently, your ISP uses carrier-grade NAT, which puts an additional
NAT router between the Internet and your router.  The resulting "double
NAT" could be your problem.

   You could try asking your ISP if you can get a public address.  They
might charge extra for that, if they'll do it at all.  Some ISPs dislike
servers for residential customers.
