DHCPV6 does not work with L3 Interfaces (tun_wg)
0%
Description
If i use the tun_wg interface with DHCPV6 to push prefixes to peers DHPCV6 stops:
/services_dhcpv6.php: The command '/usr/local/sbin/dhcpd -6 -user dhcpd -group _dhcp -chroot /var/dhcpd -cf /etc/dhcpdv6.conf -pf /var/run/dhcpdv6.pid em1.172 tun_wg0' returned exit code '1', the output was 'Internet Systems Consortium DHCP Server 4.4.2 Copyright 2004-2020 Internet Systems Consortium.

Already asked for package support here: https://github.com/theonemcdonald/pfSense-pkg-WireGuard/issues/79
But this is a more general issue. It should be no problem to use DHCPV6 with L3 interfaces.

Last I saw, WireGuard on FreeBSD did not support broadcast/multicast traffic yet. DHCPv6 may work on L3 interfaces but odds are it doesn't work on WireGuard specifically due to that behavior.
If it does work, then something may need changed upstream in ISC DHCPv6 to allow that type of interface, but either way, unlikely to be anything fixable here in pfSense.
