Dynamic DNS update cadence in 20.0?

I could swear that back in the day (maybe 18.5 or 19) that DDNS updated every five or 10 minutes and you could see this in the logs. We were using Google -- which has now sold its business -- and have switched to Cloudflare, and I'm not seeing any updates. Should it be updating (and logging) every few minutes?

If not, is there a way to force SFOS to test the mechanism to make sure I have the correct key, etc?

(The IP from the ISP is not changing and hasn't changed in years, so forcing it to change and trigger a DDNS update isn't going to happen.)

  • What I've heard from Sophos so far: They have a sample Google DNS account and were able to test DDNS with Google and it works as I remember. They don't have a sample Cloudflare DNS account, though. Unfortunately, the SFOS Cloudflare agent wants the account's Master Key (which gives total access/control over your Cloudflare account) rather than using the specialized DNS API Key, so I wasn't comfortable giving them this key to test on their system.

    What DDNS service are you using? Google, Cloudflare, other?
