Update 2.7.2 to 2.8.0 Dynamic DNS not working with Cloudflare

power_matz

@stephenw10 Just to clarify: I am still using the old module, not the new if_pppoe kernel module for PPPoE client

stephenw10

Ok. It may still be the issue though as the pppoe code was changed to allow both connection types.

power_matz

@stephenw10 Just configured another DynDNS Service and switched to the new if_pppoe kernel module. The problem is still there

stephenw10

Only after switching to if_pppoe?

Which interface are you using pppoe on? The actual 'wan' interface?

power_matz

@stephenw10 before and after switching. Just wanted to confirm that the new if_pppoe module is not the culprit.
I am using the 'wan' interface

Hello.
I am experiencing the same faulty behavior.
When debugging the PHP-Command in pfSense, it returns an IPv6 in my case.

stephenw10

When querying pppoe0?

djstone

@stephenw10
Yes.
Still quite common in Germany. (V)DSL so it's based on pppoe.

Dynamic DNS updates stopped working just as 2.8.0 was installed. Quite a bummer for me because I am heavily depended on that function.
I also tested it with the old pppoe driver and the new one - same behavior, despite I am not using cloudflare.

stephenw10

Do you only have an IPv6 address there?

I'm using PPPoE over VDSL here and it work fine. There must be something else in play.

stephenw10

Is your upstream gateway shown as online?

In 2.8.0 (and 25.03) dyndns update will fail if the gateway is offline.

djstone

@stephenw10
Nope, it's dual stack (IPv4 and IPv6)

djstone

@stephenw10
It's indeed offline.
I just changed it to unmonitored and, who would have thought, the DynDNS update is working again.

djstone

@djstone
ok, I'll have to correct that statement - IPv6 worked. IPv4 shows "0.0.0.0" as IP.

djstone

@djstone
I think the cause for the IPv4 address not updating might be, that I already did it via another service. Will restart the pppoe connection and see if it comes back to live correctly.

djstone

Ok, so far the gateway status seems to have been the root cause. Thank you for your fast response.
It would be nice, if one checks "verbose" on the Dynamic DNS configuration, to actually receive a verbose ouput or at least a hint to why the update failed.

Last thing I see me having to do is dig into the php source code to find the possible causes.
Thanks again.

stephenw10

Yup I agree. Let me see about adding some debugging there.

Thank you @stephenw10. That worked for me also.

Is there any news about the problem, or is there a workaround?

Trying to follow along, not tried everything you guys did but found this post and that worked for me.

Turned of Gateway monitoring only and Dynamic DNS became online at once after a force refresh.

@TheBigS try to check the option. For me worked
