Cloudflare is no issue but it cannot select and apply the interface. Painful for multiWAN/multiVPN. Yet another static route play in this solution (as once again firewall is "nothing" and doesn't respect rules).

Hi to all, i configure ddns with "native" backend, but when i select "InterfaceIPv4" for check ip metod (the interface is WAN) i recive this log "no global IP address detected, check config if warning persists".
now i change check ip method in noip-ipv4 and recive "Content for A record must be a valid IPv4 address". in all case the field "current ip" is blank

interface methods give interface IP which is internal IP. Useless.
external methods do check IP from outside, so keep changing the method and "Interface to monitor" until you find one that gives correct IP. In case of VPN, setting interface doesn't work, and static route (once again) is required.

Not sure if you got this to work but I was running into something similar. Upon checking logs it would error out because it couldn't find the dns record on cloudflare. I created the record there first, host.yourdomain.com random IP address. I then went back to DDNS setup, selected "IPv4 interface" as method and WAN as interface. Pulled the correct IP and updated it on cloudflare within a few minutes (TTL interval).
Not sure if we have the same exact issues, but this worked for me. Hope it helps.
