Currently, I'm using the Zoneedit Dynamic DNS services with PPPOE services for WAN. The Dynamic DNS clients didn't auto update the DNS Record after you reboot the server.
There was a bug report this morning about it: https://github.com/opnsense/core/issues/278
YES! I'm waiting for next release version.
Well, we haven't tracked it down yet so please don't expect a fix on 15.7.5 today.
I'm getting this with my first DDNS service entry ONLY but the others are working absolutely fine - even for the same service.
E.g. I have two service entries for Namecheap protocol; first does not work except when forced but the other does.
That may indeed be a clue. I'll note that in the ticket, thanks!
