Port forward on FritzBox 6660 cable and TUF GAMING AX6000 doesn't work

Hello,

I recently installed a counter strike 2 server on my computer to play with my friends,I tryed to forward the ports 27015 and 27016 (UDP and TCP) on bouth my routers (FritzBox 6660 cable and TUF GAMING AX6000,FritzBox 6660 cable being the main router/first router to connect to the internet and TUF GAMING AX6000 being the second router,the router that connects to FritzBox 6660 cable and to my computer).I've even allowed the CS2 server through my windows firewall using this commands in Windows Powershell as an administrator :

Quote

New-NetFirewallRule -DisplayName "CS2 Server" -Direction Inbound -LocalPort 27015,27016 -Protocol TCP -Action Allow
New-NetFirewallRule -DisplayName "CS2 Server" -Direction Inbound -LocalPort 27015,27016 -Protocol UDP -Action Allow
New-NetFirewallRule -DisplayName "CS2 Server" -Direction Outbound -LocalPort 27015,27016 -Protocol TCP -Action Allow
New-NetFirewallRule -DisplayName "CS2 Server" -Direction Outbound -LocalPort 27015,27016 -Protocol UDP -Action Allow

But when my friend tryed to connect to my server it didn't worked.

BTW my computer is running Windows 11.What can I do in order to be able to play with my friends on server hosted by me?

cable? you might share your ip with thousands of others and thus can't do certain things... what's you isp plan exactly?

on bouth my routers

There's your problem. You have double NAT. You shouldn't have 2 routers installed. It causes more issues than it solves. Id either put the  Fritiz box in bridge mode or put the Asus router in AP mode.

What network address are you giving out?

 

Is it 192.168 or some other combination?

 

You definitely do not want two routers in router mode, this causes

 

double network address translation

 

You have a local area network, behind the first local network, which makes it so much more complicated.

 

You may want to allow the fritzbox to be the router, and set the other wifi-router an access point only--no routing at all, so that it sends all traffic back to the fritzbox as it would do anyway.

 

The network activity would be useless if it just stopped at a wi-fi router, which is down stream from another router on the network, which then allows access to either local or online resources.

 

So you're slowing down your own network, and making it quite complicated to setup--port forwarding is already complicated enough, don't make it worse.

 

What may help is

 

tailscale

 

It allows, according to the Linux podcasts I listen to, accessing a local network (such as a home network) from a remote location

 

with no open inbound firewall ports!

 

Tailscale just might make this easier--and you can try it free

 

as long as the current ownership lasts

 

on up to 100 devices, at no cost.

 

Completely free for the user, I believe it's open-source, and it definitely uses

 

WireGuard

 

An open-source network protocol that encrypts network traffic, which is important as that reduces the risk of malicious network traffic, or interception.

Windows 11 will just force business to "recycle" "obscolete" hardware.  Microsoft definitely isn't bothered by this at all, and seems to want hardware produced just a few years ago to be considered obsolete.  They have also not shown any interest nor has any other company in a similar financial position, to help increase tech recycling whatsoever.  Windows 12 might be cloud-based and be a monthly or yearly fee.

 

Software suggestions


Just get f.lux [Link removed due to forum rules] so your screen isn't bright white at night, a golden orange in place of stark 6500K bluish white.

released in 2008 and still being improved.

 

Dark Reader addon for webpages.  Pick any color you want for both background and text (background and foreground page elements).  Enable the preview mode on desktop for Firefox and Chrome addon, by clicking the dark reader addon settings, Choose dev tools amd click preview mode.

 

NoScript or EFF's privacy badger addons can block many scripts and websites that would load and track you, possibly halving page load time!

 

F-droid is a place to install open-source software for android, Antennapod, RethinkDNS, Fennec which is Firefox with about:config, lots of performance and other changes available, mozilla KB has a huge database of what most of the settings do.  Most software in the repository only requires Android 5 and 6!

 

I recommend firewall apps (blocks apps) and dns filters (redirect all dns requests on android, to your choice of dns, even if overridden).  RethinkDNS is my pick and I set it to use pi-hole, installed inside Ubuntu/Debian, which is inside Virtualbox, until I go to a website, nothing at all connects to any other server.  I also use NextDNS.io to do the same when away from home wi-fi or even cellular!  I can even tether from cellular to any device sharing via wi-fi, and block anything with dns set to NextDNS, regardless if the device allows changing dns.  This style of network filtration is being overridden by software updates on some devices, forcing a backup dns provuder, such as google dns, when built in dns requests are not connecting.  Without a complete firewall setup, dns redirection itself is no longer always effective.

Thans for your advice.I did put my Asus router on AP mode and this solve a problem (i had the same user / ip for bouth computers showing up in fritzbox),but still portforwarding still doesn't work.I've clean installed windows and all the drivers and programs and still no portforward.

BTW is it normal to have the same ip address on both computer on google??

Yes in CMD in IPCONFIG my IPv4 Address. . . . . . . . . . . : 192.168.

I will try Tailscale,and come back with updates.

You may be on CGNAT. If thats the case port forwarding will never work. As the ISP is using NAT due to lack of public IP addresses on their part. 

 

That or something is misconfigured on your Fritzbox. Generally for port forwarding you need the IP address of the device your port forwarding for. The Port number(s) and the protocol (TCP, UDP, Both). Its a good idea to have the machine that needs port forwarding to either A) Have a reserved IP address in the DHCP server or B) Have a static IP that sits out side the range of the DHCP server. 

 

 

100.64.0.0 to 100.127.255.255 this is the IP range for CGNAT. If you check your fritzbox it should have IP info under the section dealing with Internet. It would be your WAN IP. If your WAN IP falls in this range then your ISP is using CGNAT.
