ipv6 forwaring issues eth0 sit1

Hi,

I am trying to run the Test IPv6 network within my subnet. I have set up a
Linux box with Tunneling and RADVD and want to use it as a gateway to 6Bone.
I have enabled IPv6 Forwarding on all the interfaces. Yet my machines on
subnet cant seem to ping other IPv6 Sites. Is there a problem in having the
Tunneling and routing done by the same host.

My Routing table on the Box looks like this:

[root@testbed root]# route -A inet6
