dyndns/cloudflare ignores IPv6 address on pppoe interface #2442

Closed ip6li closed 6 years ago

ip6li commented 6 years ago

Interface pppoe0 has one IPv4 address and one IPv6 (global) address assigned by provider. DynDNS service is configured for Cloudflare using username and api key.

Matching file /var/cache/dyndns_... contains 0.0.0.0| initially. After editing with vi and [Save/force update] Cloudflare got IPv4 address. AAAA RR at Cloudflare was not updated.

Expected behaviour: AAAA RR should also be updated.

Do you have only request prefix set for your WAN? It used to work, but now it does what is set up: ignore a global IPv6 on WAN so you need to move your Dynamic DNS to LAN.

Changed DynDNS config to internal IPv6 interface which got IPv6 address by prefix delegation. This interface is IPv6 only, which is intended.

result:

Jun 5 19:53:45 fw opnsense: /services_dyndns_edit.php: Aborted IPv4 detection: no address for igb1_vlan2 Jun 5 19:53:45 fw opnsense: /services_dyndns_edit.php: Dynamic DNS (tk6.example.com) There was an error trying to determine the public IP for interface - opt3(igb1_vlan2). Probably interface is not a WAN interface.

[1] real domain replaced by example.com

Sorry, I am confused now. Isn't Cloudflare is currently IPv4 only?

ip6li commented 6 years ago

AFAIK Cloudflare supports IPv6, also

fichtner commented 6 years ago

But the dyndns plugin does not yet know about it :)

If you want to request CloudFlare IPv6 support and / or work on it, please open a ticket here https://github.com/opnsense/plugins
