Linux IPv6 router

Could someone contact me off-list concerning setting up an IPv6 router using
Fedora (Core 11)? I have done all the things that I can find documented but
seem to have some issue when it comes to getting the Fedora box to route the
packet to the next hop (ISP's IPv6-enabled router). Fedora box acting as router
can ping6 ISP's router and other hosts on the net (eg. ipv6.google.com) but
other hosts in my local network can't ping anything except other local IPv6 boxes.

Any help will be greatly appreciated. Sorry for if this is inappropriate for
this list but I thought you guys could either help or point me in the right
direction for help.

Thanks.
-Jeff

1) is packet forwarding enabled?

root [at] st-6-kt ~ # sysctl net.ipv6.conf.all.forwarding=1
net.ipv6.conf.all.forwarding = 1

2) are there any firewall rules blocking the traffic?

root [at] st-6-kt ~ # ip6tables -L FORWARD
Chain FORWARD (policy ACCEPT)
target prot opt source destination

if there is something in the firwall flush it for testing: ip6tables -F
