And another bug IPAM 4.2. I adding ISC (4.1) on FreeBSD-10.0-amd64.
IPAM send to servers console (SSH):
dhcpd -t - cf "/usr/local/etc/dhcpd6.conf"
Sep 18 12:33:10 dhcpv6 dhcpd: /usr/local/etc/dhcpd6.conf line 8: subnet6 statement is only supported in DHCPv6 mode.
I can't add my ONLY IPv6 DHCPv6 in your systems. Your system is working only with IPv4 DHCP in that case. IPAM show me "Syntax error in ISC DHCP configuration file."
