Dynamic DNS update cadence in 20.0?

Hi Wayne,

screenshots of the theory, the practise as you have noted is very different. My XG updated the DDNS at 2258 24/5/24, the current time 0819 25/5/24.

Also, I would expected the IPv6 DDNS would have been added after the inclusion of IPv6 DHCP-PD.

As far as i remember (not using DDNS at the moment) it only protocols in DDNS logviewer, if there was a change. 

Mine doesn't change, it is sticky address I have had since I signed up with this RSP about 12 months ago after they did a network re-arrangement.

What about DHCP renewals possibly triggering the DDNS update, maybe?

At one time, it logged every X minutes. This could have been a Google DDNS thing, or it could have been an older SFOS (18 or 19). Definitely not doing it now, and I'm worried that I have the incorrect credentials and when it finally needs to fire it won't work. (And I won't be local.)

So any tip on forcing it to fire to test it would be great. (My ISP allocates an IPv4 via DHCP, but evidently reserves it so it hasn't changed in two years. But once they roll out IPv6, they might change how their DHCP (4 and 6) works.

Hi Wayne Folta  Are you referring to the below status on GUI for your existing added DynDNS?

Yes, that status. In my firewall the first three fields are blank and the fourth is "N/A". In the past (with Google), it would update regularly, and I could see the update in a log -- can't remember which one.

I have filled in the API information for my Cloudflare, but since it apparently doesn't fire off Cloudflare DDNS unless my public IP changes, I cannot tell if the Cloudflare info is in fact correct. I'd like to force it to update. (Again, in the past, Google updated every 5 or 10 minutes, I think, so I could check this status and see.)

Hi Wayne Folta  Thank you for confirmation on it, one such investigation is ongoing internally with ID NC-135613, I would suggest opening a Support case for the same to confirm it further internally, once the support case is open please share the case ID for reference to review its progress and to add internal note over it.

HI,

I reviewed the logviewer for DDNS updates and found that updates occur at 22:58:04 with two entries every day.

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.

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

Hi Wayne,

I am running DynDns.
