DynDNS ipv6 issue

dstacey147

I can't get DynDNS working correctly for IPv6, status is X and it shows a red 0.0.0.0 as the cached IP, note Service is Cloudflare (v6) below. The identical entry for ipv4 works just fine. I believe this was working prior to 2503, and if I look at my DNS records at Cloudflare, there's an AAAA record with the correct address on it.

Interface Service Hostname Cached IP Description
WAN Cloudflare (v6) @.graceynet.com 0.0.0.0 Cloudflare

I'm having the same issue, worked in 24.11 and broken in 25.03.

I put some more effort in this and added some extra logging to figure out which IP it's sending to cloudflare and it's my public IPv4 address instead of the IPv6 one.

I created an issue herehttps://redmine.pfsense.org/issues/16045).
There is also a "patch" there, but I suspect its still broken in more places. Use at your own discretion!

That explains this error in the logs

falseFeb 13 08:39:37	php-fpm	97602	/services_dyndns_edit.php: phpDynDNS (wg): UNKNOWN ERROR - Content for AAAA record must be a valid IPv6 address.

Thanks for the report. I've made a patch available for testing:
https://redmine.pfsense.org/issues/16045#note-4

This can be applied using the System Patches package.

@marcosm I installed the patch. The update now works, but it's still the ipv4 address that gets cached and what's shown in the status. Log entries below.

I tried to reply in redmine but got the same error mentioned by @bschapendonk about target version blank, he mentioned using edit but I still couldn't get it to work so posting here.

I think $this->_addressFamily still isn't set to a correct value, hence the IPv4 is cached. Also the GUI show's an IPv4 address now.
But the IPv6 is at least pushed to cloudflare.

I've updated the patch on the redmine comment to address a number of issues. Please give it a test.

@marcosm The latest patch appears to have corrected the issue. The log now looks good, and the status is now showing the correct value for DynDNS ipv6 address. Thanks Marcos!
