IPv6 Auto configure issue on FreeNAS-8.3.1-RC1-x64 (r13329

[sysfu]

I have a FreeNAS server with one network interface that is configured to use DHCP for both IPv4 and IPv6.

IPv4 auto configuration via DHCP is working properly, IPv6 is not. Every other host on the LAN is properly auto-configuring using the router's DHCPv6 server, so I'm focusing on FreeNAS to find the problem.

ifconfig <interface> | grep inet6 command shows the autoconfigured IPv6 address beginning with fe80::, however the interface is not grabbing the DHCPv6 assigned address.

ps -aux from the console shows that the rtsold daemon is not running either. Multiple reboots have not resolved the issue either nor did manually running "rtsold -F <interface>".

Manually starting the ipv6 network yields the following errors

[root@freenas] ~# /etc/rc.d/network_ipv6 restart
network_ipv6 not running?
net.inet6.ip6.forwarding: 0 -> 0

Running rtsol in debug mode yields this:

Just a comment, not sure how helpful it will be. If I'm not mistaken, bge is Broadcom NIC. Those seem to be the absolute worst for compatibility with FreeBSD. If you have any other card I'd recommend you try those and see if you have the same issue. Intel is the best card for FreeBSD, but any other major brand for troubleshooting may tell you if its a card/driver issues with bge.

Unfortunately I do not have any Intel NICs that I can test in the system. It's an HP Microserver and so requires mini-PCI methinks.

FWIW I have several other systems with Broadcom NIC chipsets that work just fine with IPv6 when running Arch or OpenBSD.
