Unable to setup dhcpv6 client

[echelon5]

I've 2 freenas boxes that I'm trying to setup with ipv6. Both have a lagg0 interface (LACP), one's running 11.2-U7 and the other 11.2-U6 . I'm fairly new to IPv6 but other devices on LAN are getting address from a pfsense DHCPv6 server with the router in managed mode.

Here's what I've tried till now:

1. I've checked auto configure ipv6 in web gui and I got a link-local address and a default name server -> no global address.
service rtsold was running

2. Added to system tunables type rc.conf:
Variable: ifconfig_lagg0_ipv6 Value: inet6 accept_rtadv auto_linklocal
Variable: rtsold_enable Value: YES

Now I'm not getting anything ipv6 related and ifconfig shows:

nd6 options=2b<PERFORMNUD,ACCEPT_RTADV,IFDISABLED,AUTO_LINKLOCAL>

service rtsold was running

3. removed variable rtsold_enable and unchecked ipv6 autoconfig in web ui.

I'm getting ipv6 link-local, default route, and nameserver, but no global address.

4. disabled ipv4 dhcp on interface and set static IP - no change

note: manually setting an ipv6 works, but I'd rather have dhcp

There are some IPv6 DHCP fixes coming in 11.3. If the issue persists for you once 11.3 is out (or if you have a chance to test during the BETA series), please create a report at bugs.ixsystems.com and post the issue number here.
