21.1 Legacy Series / Constant timeouts adding dynamic dns entries for DHCP6 clients

« on: June 25, 2021, 02:57:37 am »

Running on the current release of OPNSense (OPNsense 21.1.7_1-amd64) and getting the following errors constantly as clients obtain dhcp6 leases:

Code: [Select]

Unable to add forward map from host.home.localdomain.com to 2403:xxxx:xxxx:xxxx::a235: timed out

IPv4 addresses are registering correctly, the issue is only seen with IPv6.

Using Unbound for DNS.

Anyone have any ideas why I am seeing this?
