@wcktklwn Can you provide vyos config for dynamic service and config ddclient.conf
Which lines do you add manually?

Here is the vyos config.

service cloudflare {
    host-name example.com
    login [email protected]
    password password
}

When it generates the ddclient.conf file it puts in like this,

# DynDNS provider configuration for example.com
protocol=cloudflare,
max-interval=28d,
[email protected],
password='password',
zone=com,
example.com

and I have to modify it to look like this. (only the zone= line is changed)

# DynDNS provider configuration for example.com
protocol=cloudflare,
max-interval=28d,
[email protected],
password='password',
zone=example.com,
example.com

Unfortunately I have no idea how that zone option works. I'd rather solve this by an automatic code path then specifying it on the commandline (which is now possible).

Can we always assume that:

hostname example.com -> zone example.com
hostname foo.example.com -> zone example.com
hostname bar.foo.example.com -> foo.example.com? or example.com?

Once there is some light in the dark we can probably automate this.

Please test latest rolling so far.
