6bone access from behind NAT

[Dan Perry]

Hi all,
	I'm trying (unsuccessfully) to connect a small network of
windows 2000 machines to the 6bone.  Originally, I had one machine
running the standard Windows NAT service, and that server had one NIC
connected directly to the DSL line, and the other to the private
network.   I had that server running as a 6to4 router, and everything
worked fine.   However, I've since replaced that server with a common
hardware cable/DSL router.   I've configured that new router to forward
all incoming packets to the old server.   The old server current has one
NIC now.   
	I've been trying to use freenet6's tunnel broker service to
connect to the 6bone.   At first this failed as the server had a private
IP.  However, I changed the tspc.conf file to include the external IP
provided by my ISP as the v4 address used for the tunnel.   After doing
this, the tunnel seems to set itself up properly.   However, I'm not
able to ping anything but the server, or any other machine with IPv6 on
my private network.   Can anyone point out something that I need to do
in order to get this to work?

Here are some outputs from the command line on the server I'm trying to
create a 6to4 router on:

As you can probably tell, I'm relatively new to IPv6, but any comments
or suggestions would be greatly appreciated.

Thanks,
