Title: Dynddns can't determine public IP
Post by: kjp4756 on July 18, 2020, 02:34:18 am

OPNsense 20.1.8_1-amd64
FreeBSD 11.2-RELEASE-p20-HBSD
LibreSSL 3.0.2

I'm trying to get dyndns working with cloudflare.  I have a simple set up with just a static ipv4 ip (ipv6 is disabled).  I get the following error in log files when trying to update cloudflare.  The overview page under interfaces shows an IP.

opnsense: /services_dyndns_edit.php: Dynamic DNS (xxxxxxt) There was an error trying to determine the public IP for interface - wan(vtnet1). Probably interface is not a WAN interface.

Does your WAN interface have an RFC 1918 IP address?

No it doesn't.  It's a "real" IP.  235.xxx.xxx.xxx.  Strange thing is; I used to use the namecheap dyndns setting and that one works without trouble.  The cloudflare v6 token doesn't appear to work for me.

Got it working using the "Cloudflare API Token" service rather than the v6 one.

EDIT:  I see what happened now.  v6 refers to ipv6.  Of course that won't work for me with ipv6 disabled.  I thought the v6 referred to the api version or something.
