Router Behind NAT

Hello everyone, I have few self hosted services on a local server that's connected to the internet though a 5G router (which usually is behind NAT) and can't get a real public IP to create a DNS record or a DDNS... what is the best way to do that?

Cloudflare tunnels would be a good solution for this

Cloudflare Tunnel · Cloudflare Zero Trust docs

Cloudflare Tunnel provides you with a secure way to connect your resources to Cloudflare without a publicly routable IP address. With Tunnel, you do not send traffic to an external IP — instead, a lightweight daemon in your infrastructure (cloudflared) creates outbound-only connections to Cloudflare's global network. Cloudflare Tunnel can conn...

You run a piece of software on your local server, that connects out to Cloudflare, then any requests that come in go through that tunnel, meaning you don't need to open any ports on your network.

Right, if the tunnel is down it wont be able to forward the request.
Could you elebaorate on your question? Are you confused why you're seeing the message? Or are you asking if it's possible to change the message?

I believe (though I haven't verified) you should be able to change this error page with custom error and challange pages: https://developers.cloudflare.com/support/more-dashboard-apps/cloudflare-custom-pages/configuring-custom-pages-error-and-challenge/
Note that this does require at least a Pro subscription.

Cloudflare uses a wide range of error codes to identify issues in handling request traffic. By default, these error pages mention Cloudflare; however, custom error pages help you provide a consistent brand experience for your users.

Plenty of professional sites use CF tunnels to host their website, that shouldn't be an issue.
Hosting from home is a bit risky if you are doing anything serious. It's much more likely for your power or internet to go out at your home than at a datacenter. That being said, for personal project it's totally fine in my opinion.

Note that if you're hosting a static site, or using a Javascript framework, Pages/workers assets allow you to host those on Cloudflare directly, for free.

You're the best... thank you very much, I'm actually using Flask as backend, But it's just a family website nothing very serious... the data are very valuable but only for me and my family members... so self-hosting in my home lab is best option for me... thank you again for your help and response

hello all..i am new to this channel and not very well versed on the zero trust tunnel BUT i created one several months back for a service i am running at my home and im behind CGNAT. It worked perfect for about 4 months then i was checking on it one day when i couldnt access it from anohter device and a message said i needed to change NS. Which i did. I also made sure DNS records were good. Now i cant connect to the server. an NSLookup resolvs to cloudflare and the status says healty uptime 55 minutes. oh yea, i did renew the token and uninstall/reran the service on my win11 box. Any ideas why i am not getting a connection is there something with DNS i may have overlooked? thanks in advance
