Do you have a host-based firewall running? ip6tables perhaps?
ip6tables -L

Subject: Problems accessing www.ietf.org over IPv6
I have a /48 native IPv6 prefix routed to my home lab.
I come back from IETF, and Firefox 3.0.6 is hanging accessing
www.ietf.org on my duo-stack Centos 5.2 laptop.
I do a ping6 and can get to www.ietf.org, so it is not a routing
problem. I run wireshark and I see IPv4 and IPv6 tcp sessions.
In the end I have to disable IPv6 in Firefox to get to the ietf home
page. Doesn't see right, I had no trouble with this at the meeting and
all I did was suspend my system to go home. I rebooted here (horrors,
rebooting a Linux system) jsut to see if there was something hanging
around from ietf.
