Entering DDNS info for Cloudflare

Using OpenWrt 19.07-02 and can't find out where in the GUI one would enter attributes like domain, userid, password, etc. for Cloudflare to manage it.

I saw mention somewhere to go to Services->DDNS but I don't see it there. So, I updated file /etc/config/ddns-opkg a while ago and later my IP changed but cloudflare did not get updated. I have installed curl and ddns-scripts_cloudflare.com-v4.

Thanks, Rich

do you have the luci-app-ddns?
also you need to change the ddns config file ... ddns-opkg is not used

No sir, but i just added it.

Now it shows up under Services

I created an entry but don't know how to test it. Any clue?

Enter the data and check the log
Or just ping the address and check the ip

My OpenWrt LAN router( WAN side) is behind my FIOS Gateway router( LAN side) so it seems to be using

Would you know how to get around that?

Not sure if this is an error or if OK from log

It seems to be telling you the email address format is wrong. I see X-Auth-Email: flowersrj, guessing that might be what you put in the username field in Luci? Try putting your full email address that you use with Cloudflare in the username field instead.

Still same results after trying my eMail address

Mine look like this, just in case it helps:

My situation might be unique.
"richnpeg.us" resolves to an AWS location" for a website
"home.richnpeg.us" resolves to my WAN IP.
I am using Cloudflare to manage them both.

In OW, I have these relevant values ...

under Services->Dynamic DNS->Basic settings
Lookup Hostname: home.richnpeg.us
DNS service provider [IVP4]: cloudflare.com-v4
Domain: richnpeg.us

under Services->Dynamic DNS->Advanced settings
IP address source [IPV4]: URL
URL to detect: https://cloudflare.com/cdn-cgi/trace
Event network [IPV4]: wan

See anything you don't like?

I guess it should be like this:

Domain: home.richnpeg.us
URL to detect: http://checkip.dyndns.com/

Hey, @flowersrj,

@AndrewZ is right. In previous post I gave you the URL he is giving you in his post, and no, your scenario is not unique, it is exactly mine. In any case, I think the problem is something else, as your computer is reporting a local IP.

Do you mind to flick me your config file, please? Cleary, something is wrong on your side. Are you in a double NAT scenario by any chance?


OpenWrt is on a LAN router (wan side=, lan side= behind a FIOS gateway router(lan side= So, I would say yes. everything else seem to be fine.


I don't have dyndns.com.

Me too. That is completely unrelated.

Hi, mate,

Here is mine, just do the same, and yes, you are using double NAT. Anyways, this configuration is working, your option domain clause is wrong, check mine:

config service 'Cloudflare cuantufatu.com example'
	option lookup_host 'home.cuantufatu.com'
	option service_name 'cloudflare.com-v4'
	option use_https '1'
	option domain 'home@cuantufatu.com'
	option username 'user@gmail.com'
	option password '6bbd01c2548ed9934b84c215472e7674efd3'
	option enabled '1'
	option use_ipv6 '0'
	option cacert '/etc/ssl/certs'
	option check_unit 'minutes'
	option force_unit 'minutes'
	option retry_unit 'seconds'
	option interface 'eth0'
	option ip_source 'web'
	option ip_url 'http://checkip.dyndns.com'

It was Deleted.

So, there is something different:

 065301       : #> /usr/bin/wget-ssl --hsts-file=/tmp/.wget-hsts -nv -t 1 -O /var/run/ddns/my_home_ipv4.dat -o /var/run/ddns/my_home_ipv4.err --ca-directory=/etc/ssl/certs --no-proxy 'http://checkip.dyndns.com'

I am using wget for it, if you are using SSL you have to install ca-bundle and ca-certificates, and to mimic my config it will not hurt to install wget, just in case.

Fixed. Turns out it was the password. I was using my :grinning:account password not the global API token.

Thanks for everyone's help.
