I’ve experienced the same DNS “bug” when deleting a tunnel and needed to manually delete the DNS entry to reuse the subdomain when I started setting things up and testing. However, later when I set up different tunnels and eventually deleted them after testing, the DNS entry was deleted with the tunnel. So it hasn’t been a consistent bug for me, and may be related to the process taken when deleting.

@JamzYaneza Жыл бұрын

I encountered that small nuance of not being able to adding back/renaming to a hostname that I had previously used. When you create/add a Public Hostname under Tunnel it creates a new CNAME in your DNS, and this doesn't get automatically deleted probably more of a safety feature since DNS propagation usually takes time. Delete the CNAME entry and you can go about the rest of the day.

I'll have to give this a try. I actually had to solve this exact problem for a server I was building last year.

It follows the iptables rules to forward specific traffic over the zerotier virtual network to the local vm's and back.

Hi Tom. Thanks for this great content! I successfully use CF tunnels to expose home services a good while. Using "Applications Policies" in conjunction with "Access Groups" give me a granular way to lock down certain services to special groups of users or devices (by country, ip-address ranges, e-mail addr). Using special "identity provider"s for certain applications provides more flexibility also. The use tunnels depends a lot of "trusting" CF. Controlling the SSL-endpoints is a real responsibility for CF. Hope that CF never suffers a data breach or use our data for their own purposes. Than the "shit hits the fan"... A good an successful year 2023 for everybody! See you next year (in 1 day) 😀

Tailscale or Zerotier are overlay networks , this is a reverse proxy they are not the same thing at all.

@Nonkel: Main difference: With Tailscale / Zerotier the end point needs to be setup, here you do expose a servive to the internet, they great advantage: you do benefit from all security cloudflare provides, compared to a (mis)configured firewall at home. however without the shown security layer from Tom, you need to trust the implementation and setup with the client. Also too: The fact CF can intercept all traffic is a downside for me. Apart from media streaming I wouldnt know, what I want to share with them... although someone above explained to achieve real end2end (by pointing to a CA i think)

Great video ! I set policies to "email" for each of my services. Is it a bug that once I succesfully accessed one service using the emailed PIN, I can then access all of the other services on the same tunnel without being challenged for an email PIN ? Or does the browser store a cookie allowing access to all services once I have successfully accessed one of them ? If I set a different email address for each service then this "bulk authorisation" disappears. I found that setting the "session duration" to "no duration" prevents this behaviour.

Hey there. Not sure if you’ve figured out the bug already, but in case you haven’t. When you create a new public hostname, it’s actually creating a new CNAME entry in your DNS records. When you delete a tunnel before the hostname, you just need to go delete the DNS entry manually before you can recreate one of the same name. Deleting the public hostname “correctly” simply removes the DNS entry for you. Hope this helps!
