My wireless interface is set to automatically for IPv6. I have DHCPv6 configured in my pfSense firewall and my Windows 7 machine receives a DHCPv6 address just fine. However, my OSX (Lion, 10.7) Macbook Air never receives anything but a link-local IPv6 address. Ideas or suggestions? (EDIT) Here are the pfSense DHCPv6 options, I am using managed: said by pfSense 2.1 : Use "Router Only" to only advertise this router, "Unmanaged" for Router Advertising with Stateless Autoconfig, "Managed" for assignment through (a) DHCPv6 Server, "Assisted" for DHCPv6 Server assignment combined with Stateless Autoconfig It is not required to activate this DHCPv6 server when set to "Managed", this can be another host on the network.

I believe this is equivalent to pfsense's ""Unmanaged" for Router Advertising with Stateless Autoconfig" But I no longer run this way, I prefer to assign IPs statically.

whfsdude Premium join:2003-04-05 Washington, DC Reviews: ·T-Mobile US	reply to Matt Running pfsense w/DHCPv6 and SLAAC. My 10.7 boxes pick up the DHCPv6 address and SLAAC just fine. I end up w/three addresses: 1. SLAAC 2. SLAAC-PE 3. DHCPv6 I have mine set to Assisted as I want all three but I have tried it via setting the managed flag and works fine (except for my mobile devices that only support SLAAC). I'm also running - 2.1-DEVELOPMENT (amd64) built on Fri Nov 25 22:55:21 EST 2011 I would check to make sure that PC is actually getting a DHCPv6 address and it's not Teredo. I would also run a tcpdump on the Mac and see what the router advertisements are showing. Keep in mind RA's are still needed so if multicast is broken somewhere on the network, DHCPv6 won't work. sudo tcpdump -i your_int -vvv ip6

Yes, which is why I am here. The results that popped up were old and some (around Lion) were conflicting.

My PC is definitely getting an address from me HE.net /64, as I can query their DNS server and I pass the ipv6test.com test from it. I'll give your other suggestions a shot shortly, thanks for the tips.

I am wondering if you're getting hit w/ that bug. Does pfsense show any v6 leases? I'm wondering if the PC could be getting SLAAC instead of DHCPv6.
