I ended up using Vyatta as my firewall since it fully supports IPv6. I
played around
with ip6tables in CentOS 5.5 and noticed that it seemed to be missing some of
the stateful features like the recent module. Vyatta works flawlessly
with IPv6 and
the config syntax is easier than straight iptables. I'm assuming
CentOS 6 will work
great once it comes out.
