Hello I've tried to port forward the port 27015 for my csgo server but it does not work...

I have the Sagemcom f@st 5670 Router.



-I have a static Ip

-I checked in cmd with the command netstat -a and saw that the port is listening

-I've tried couple of ranges to port forward for the server

-I called the ISP for help and there is no block on the ports

-I've tried to activate dmz

-I've tried to restart the router after port forwarding

-I created rules for the ports in windows firewall


This is not the first time I am using port forwarding for my csgo servers but with this new router I really got frustrated. I will appreciate any help to fix that problem.

The port that I created:
https://prnt.sc/4cNJ975xqqCl

You have a static IP on what? The PC or the public IP on the router ?
Have you verified that you have a public IP address by comparing the WAN address of the router to https://whatsmyip.com/ ?
 
he could port forward with host name and dynamic dns
try with no-ip it should be free
basicly you will be running domain client which will be updating your current IP on your domain
then poeople tryin to play on your server wont need to know your IP, theyl just use domain adress instead of ip adress
 
Your router is tough to find good manuals or screenshots.

My guess is look at the field that says "public IP". Check that this IP is the same as whatsmyip. Your other option is to just look around for IP addresses. Your lan is likely 192.168.1.1 or 192.168.0.1. You want to find a different IP. That should be the IP the ISP is assigning to your router.
The key here is private IP are generally 192.168.x.x. 10.x.x.x or 100.?.x.x or 172.1x.x.x

You are getting ahead of yourself. DYNDNS is used when you have a public IP and it changes but if you are being given private IP rather than public you can't use dyndns either.

What i've found is what you mentioned: 192.168.x.x. 10.x.x.x or 100.?.x.x or 172.1x.x.x , The only thing that include public starting with 100 and its the public Ipv4 address...

So because I can't find and compare the public ip address and the wan address of the router that what causing ports not to work and be open?
 
If you have a ip address assigned to the wan of your router that starts with 100. It is highly likely that is a special form of private IP that is designed for ISP to use. They do this because IPv4 addresses are in short supply and most users do not need one.

Your only option is to contact your ISP and see if they will assign you a public IP. Some ISP will do it just for asking other want a extra monthly fee and some do not offer the service at all.

As stated above the public IP you see on whatsmyip is assigned to another router in the ISP network. You would have to put port forwarding rules in that router which of course you can't.
