OK for the life of me I cannot get this to work correctly and the only posts on the internet are about a decade old and don't have full or correct directions.
I've got a FritzBox 7490 on 2Degrees and I used to use Namecheap for my DNS and their Dynamic DNS feature to update the Fritzbox using a custom URL. Worked fine.
However, I need to move my DNS to Cloudflare and I can see that the preferred method is to use DNS-O-Matic as the update agent and then DNSOMatic pushes the update to Cloudflare.
Everything I have found is that after you have setup Cloudflare and DNSOMatic (DOM) you use the following custom URL on the FritzBox
https://updates.dnsomatic.com/nic/update?myip=
Enter the FQDN into the domain field and then your opendns username (which is your opendns email address) and password.
It works, but the problem is when you don't pass a hostname variable to DOM, they update EVERY hostname in your DOM account to that IP. That's a problem because I have multiple dynamic hostnames so I only want the specific hostname to update. I have this working just fine with my Asus router where it only updates the defined hostname.
For the life of me I cannot get this Fritzbox to play nice.
The official DOM API docs say this is the format
The FritzBox docs state that you can form your own custom URL and they give you the variables to form it including the <domain> field https://en.avm.de/service/knowledge-base/dok/FRITZ-Box-7490/30_Setting-up-dynamic-DNS-in-the-FRITZ-Box/
I've tried
http://updates.dnsomatic.com/nic/update?hostname=<domain>&myip=<ipaddr>&wildcard=NOCHG&mx=NOCHG&backmx=NOCHG
https://<username>:<pass>@updates.dnsomatic.com/nic/update?hostname=&myip=&wildcard=NOCHG&mx=NOCHG&backmx=NOCHG
Nothing will actually get anything to update at all.
Anyone else using DNS-O-Matic on Fritzbox?
