Roues and OS X Server

[tlockley]

I have an OS X 10.5 Server that I am using as my core DHCP/NAT router and I want to start working with IPv6 on it. I can get a tunnelbroker tunnel working but when I activate the route to pass data over the IPv6 tunnel, it causes the NAT setup to stop working. Is there a way to have an IPv6 tunnel that will only function on the server and not ruin my NAT/Router setup?

I guess I'm not sure what you mean by "it causes the NAT setup to stop working"

Can you provide a little more detail?  If you could post the commands you used to set everything up, it'd help too
