IPv6 has been working fine for a few months. After updating to the latest OPNSense release, none of my clients can obtain IPv6 addresses. The configuration looks correct and OPNSense is getting a prefix from my provider (Verizon FIOS). DHCPv6 is running, but shows no leases.

My LAN is set to track interface mode and ifconfig shows the LAN interface is being assigned IPv6 addresses. One possible issue is the file /etc/dhcpdv6.conf does not exist. I tried changing the LAN IPv6 config (IPv6 Prefix ID) to see if the file might be regenerated, but no luck.

Suggestions on how to debug this?

Adding ifid to /var/etc/dhcp6c.conf is overwritten and ignored. Is there a place in the GUI for setting this?
