CloudFlare DDNS - Update CloudFlare with Your Dynamic IP Address

I encountered a weird issue... My Oznu updater picks the wrong WAN on my router, however under the same subnet everything is routed to a specific one and i do confirm that every other vm, container etc routed throu this one except the oznu ddns updater. Why on earth does the software picks the wrong connection? Can you help me out?

It worked but how do I set it up to run every couple minutes? Or does it already do this

Thanks! This worked perfectly

i've been lost since the point you copied the token. got no clue which site suddenly shows up there where you pasting things in an stuff. so sad 😞

Many thanks, most helpful. I like this solution; was using ddclient before but it does not work with Cloudflare.

Excellent video! No unnecessary monologuing like some guides do.

Kudos for your excellent tutorials. My NAS is connected to NordVPN. Therefore, the containers communicate the IP address of the VPN and not the IP of my ISP. Therefore, when I create the tunnels, I can't reach those containers or the DSM. However, if I change the service order on the NAS by putting the LAN first, then the connection is immediate and I access, for example, the DSM without problems (I do not access the other containers instead). Is there a way to route the traffic from the VPN IP to the LAN IP so I can log in seamlessly? This video somehow lit a light bulb for me, but I have no idea if I'm on the right track! Thanks in advance.

I have a reserved ip how can i access it from anywhere

Too quick, not describing what you're doing.
Copied some docker-compose code from somewhere not explained.
Stated that PUID/PGID settings are for your setup, but not other peoples. So what do we do?

Hello, I think you miss the part where you put the code on Docker. Can you please explain what to do in docker before putting inside the code from cloudflare? Thank you! :(

man, you are on Cokeine 😂😂😂

hello brother can you tell me how to add subdomain ? i can add 2 /3 subdomain but always 1 domain update but others not updated.. wait for you replay

Does this image actually connect to cloudflare to verify the real IP before updating? Because a curl will always return the proxied IP. No mention of any sort of interval on the update either.

This video is 2 years old and so is the container image that is being recommended here. I suggest using the qmcgaw/ddns-updater image instead. The setup is a little different and you'll have to set it up in a config.json, but the container image is regularly maintained and supports a wide list of DDNS providers not just Cloudflare. Using the video and that image I was able to setup a subdomain that gives direct access to my home so ssh and wireguard work while still having everything else proxied.

THANK YOU!!!! YOU SAVED MY DAY !!!

good stuff

Excellent video. Right to the point. I've been struggling to set exactly this until I found your video. Thanks!

Thank you 😁 another great tutorial!

Hey DB, Thanks for this video, it's gotten me soooo close to getting DDNS up & running for my first time. However, when I look at the stack logs I'm getting a "curl: (60) SSL certificate problem: self signed certificate" error. Did I setup proxmox, docker, portainer, or cloudflare container incorrectly? Or is it something on my Cloudflare account? I've seen that you can add a tag to ignore the SSL requirement, but how can I do that in a Docker Compose and are there security implications to doing that? I'm sooo close. Thanks again, loving your content.

Wtf is that? can u pls make tutorial without fkn docker, just simple linux script?

Thanks alot, your videos are really helping me learn alot of things !
Also, the PUI and PGID is not a requirement anymore !

I tried but I noticed it does not work for free domains like those ending in tk ga etc. Just for the paid ones. If someone knows how to make these free domains to update with another programs, I would apreciate it. Thanks.

super video is this working also if my router is behind the ISP dinamic NAT?

Nice. Still useful tutorial to this day. The only thing that I have to do as extra is to add another separate service in the stack for wildcard subdomains, because I am not sure how to to do it in a single service. Do let me know if anyone did know how to do it.

Excellent video. Question. Can I add multiple "zone" parameters in the docker compose file to update multiple domain names? If so, do I just add the "zone" variable twice, or do I use a comma and put them both on the same line?

Good explanation

Thank you very much! Helped me a lot! :D

Wait I have a lot of questions about this step. Like do I need to buy a website domain name to actually do this step and I can I use that domain name over the internet? I'm debating if I need this step or not. Thanks for any Reponses!

Another great video and certainly the cleanest way to resolve a dynamic IP, keeping it all within Cloudflare. I'm achieving a similar result with Cloudflare by watching one of your other videos on installing Duck DNS on OMV. Then on Cloudflare's DNS, instead of entering an IP address, I just entered my Duck DNS address. Cloudflare then retrieves the dynamic IP address from the Duck DNS address.

Thanks 👍👍👍

How do you do this with wordpress?

It's not working for me unfortunately. On the docker logs, I am getting the message:
'error: failed to update cloudflare dns record <domain> from <IP> to <IP>'

thank you for the content you do a really good job. but i see the your always racing the time 😓

Great video... terrible sound problems, skipping most of the time. You are great as always on explaining cool stuff though.

For someone who gets a new public ip everytime my router restarts i cannot thank you enough for this simple yet effective solution! :)

great info.. I wish when people were doing demos like this they would just slow down a bit... yes I can play the video at a slower speed but you're just clicking around too fast for me to follow along.

Brilliant overview, worked perfectly! Thanks so much

Any help with automatic updating the AAAA record

Lost me me at, "Move this over there" not familiar with Docker stack

Another great video. This was an easy one to do. Thanks!

Hi I am totally new to docker and linux where and how are you getting to the screen where you open up your stacks ?

Thank you for this awesome guide. I have a problem when my firewall is enabled. May I know what port should I add in my firewall? Thank you!

Hello David, I was wondering if you could do a tutorial on "How to Set up Cloudflare Argo Tunnel" on Raspberry Pi (Portainer) to - Bypass CGNAT and ISP Port blocking, Thanks.

I tried your method, but it keeps failing (I think that this happens because I'm using free domains)
Is there any workaround for this issue?
