Description

I am on pfSense plus 25.11.1 on a 6100 max. My ISP provides a /56 DHCPv6 prefix delegation (see screenshot). I use "track interface" for IPv6 on my LAN interfaces and all IPv6 connections/address assignments are working as expected.

However, when setting up OpenVPN, when I choose the "track interface" option and specify an IPv6 prefix id (see screenshot), the resulting IPv6 server definition is not correctly updated in the OpenVPN config file (see screenshot).

Please also note the end blank on the "(hexadecimal from 0 to )" on the OpenVPN prefix id settings verbiage. So it appears the IPv6 "track interface" option is not working for OpenVPN.
