I've finally gotten around to upgrading my local network to IPV6 (following this guide: http://doc.pfsense.org/index.php/Using_IPv6_on_2.0) via an HE tunnel. Everything worked pretty much immediately (several win7, a mac pro, and Ubuntu pc's) and got new addresses from the assigned /64 block. They are all able to reach test-ipv6.com and ipv6.google.com without issue.
The only machines that don't work are my two Arch PCs (laptop(wireless) and a desktop(wired)--both using Networkmanager). They only seem to be able to get link-local (fe80...) addresses. I've verified that the respective connections are set to IPV6: automatic. I haven't tried disabling Networkmanager, but I see no reason it shouldn't work as it works under Ubuntu. I definitely don't profess to be an IPV6 expert (or an Arch expert for that matter)--I'm doing this for my own edification and I fully expect I've committed a trivial error. I was curious if anyone else had experienced similar issues. All the Arch IPV6 examples I have seen haven't involved networkmanager and indicate that IPv6 should work out of the box--even (or especially) with NM. Any insight is appreciated.
I'll include lines from my daemons.log and ifconfig:

Sorry, posted too soon. I had the DHCPv6 server on the pfsense box set to 'Managed'. I changed it to 'Assisted' and the arch PC's started working. MY understanding is that the only difference between the two is stateless auto-config. Any clue why only Arch had a problem with this?
