I think it’s important to note that cloudflare tunnels have limitations. For exemple if you plan to use this to access stuff that require large file transfers like nextcloud, cloudflare tunnels are limited to 100mb per file.

Thank you for this info.. that adds a lot of doubt into the mix for if I want to use it. I have large photos, videos and PDF documents that exceed 100MB Maybe Cloudflare wants a client to upgrade to get a higher threshold on the file sizes?

thanks so much for your detailed videos - I have been struggling since last couple of days to fix the cloudflare tunneling problem with my docker container and continuously watching videos on youtube. But your video help me to resolve the issue, thanks again.

This service is brilliant, I had superficially seen something about it, but I hadn't tested it yet, now with this video, I'm going to try to implement it in some personal project to test it and see if it fits in some current or future project!

Thanks for the tutorial. I was able to set this up to point to my Plex server and Owncast instance. I previously had these behind an nginx proxy. Plex and Owncast use websockets and was tricky to configure all of that in Nginx. Using Cloudflare tunnels, everything just works! no more nginx reverse-proxy configs and struggling to get it configured correctly.

It's hilarious how many times in the past year I've search this up to bypass ISP port blocking, and still haven't done it... maybe this will be the recemented video that makes me implement it.

Many thanks. Will certainly be looking at this and interesting you referenced it re Bitwarden which is one of my potential use cases. Originally I was going to do bitwarden self hosted with vpn. Cisco CBD build to be done next week too.

I'd love to see you run your ssh connections through a tunnel. I've only managed to do it with their in-browser ssh client, and not through a remote terminal.

Saved me for an issue I was having, thank you very much!

I run this as an add on in Home Assistant, works great!

@Tom thank you for this.. you solved my issue.. I wasn't activating the "No TLS Verify" so it wasn't working..

thank god for u, everyone missed the tls setting

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.

Awesome video Lawrence, you got me out of a pickle, unfortunately, I followed another youtuber's video, but he failed to provide one very important detail regarding TLS verification..! Thanks

Super helpful! Thank you!

Thank you for this video. Answers a lot of questions I have :-)

Externally (for the end user), the certificate still says Cloudflare

Excellent demo! Question do they offer an agent that would enable private tunnel access with 2fa? This way you could enable access to all containers with a wildcard and not expose all the names in public dns,

If you go into your DNS settings in cloud flare for that domain you can remove them manually if you do it backwards.

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) 😀

This worked excellent. So many layers and no holes in the firewall.

Damn… I already thought I must have a look at Cloudflare Zero Trust Platform, but still havent come around doing so. Thanks to this video, I now know I DEFINETILEY need to have a look at as soon as possible…

Thanks for this video, cloudflare is the best 💯

It occurs to me that this might be a way to "expose" my webserver to fellow residents of the retirement village I live in and build a community portal. I'm behind a double NAT and I'm running WordPress on IIS (because I know IIS...). Thoughts on using Cloudflare Tunnels for this purpose?

Awesome video ! Thank you very much !

Great video as always. Is there a way to create a RTSP stream connection to an internal camera?

I'll have to give this a try. I actually had to solve this exact problem for a server I was building last year. I ended up using zerotier sdn connecting the homelab vm's to a droplet with a public IP, and using ipforwarding and ipchain to build a frontend for it. the droplet has the ssl cert, and dns records pointing to it. It follows the iptables rules to forward specific traffic over the zerotier virtual network to the local vm's and back.

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.

awsome. I saw it elsewhere, but not seen the additional security layer. there is only the risk that cloud flare going for the free security to paid in some years.

Cloudflare tunnels, this is the way. Also the Web Application Firewall (WAF) they offer for free only adds additinal layers of security. You can make firewall rules to block traffic before it ever hits your network/servers/applications.

Hi you are great!! it's possible protect the tunnel access with mutual tls for authenticated the clients? because the apps behind the tunnel has auth. like a "MFA" cert + user + pwd

Great Vid, what about set up for a RDP connection? I can't seem to get this to work

Hello, this is a great video and convinced me to use Cloudflare Tunnels instead of reverse proxy. A question though: is there a possibility to add wildcards? I want to run a Wordpress Multisite but dont want to log in to Cloudflare and add another tunnel every time I add a new site. Also, if there are issues removing a tunnel I may have to rethink this.

Hey Lawrence, just wondering if you've tried the client configuration option (versus configuring on the zero-trust dashboard). I suspect you'll find this more helpful and it may also address the "bug" you mentioned in the video (at end).

@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)

Any particular reason to use this instead of Tailscale? Apart from needing Tailscale on both the server and the client?

I do use it from before it changed of name. It was in beta, right now why it is free it is for gaining clients also if they do updates it is on the free before as if it broke the payed clients wont get the error as they will correct the error before. I used it for years as I am hosting at home on DHCP from my ISP and with it changing IP wont do me any thing. It is super repliable, safe and easy to configure.

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.

This is one of those awesome tools similar to ZeroTier One that once you hear about them you are super glad you know exist!

That looks really interesting, I'm currently using wireguard on pfsense, but I'll definitely have a play with that. As always, thanks for your excellent videos.

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!
