I've been trying all sorts of combinations to get IPv6 traffic to go out the PPTP VPN that I've setup on my Mac OS X 10.6 machine. I have the 'VPN is Tunnel Endpoint' checked in the Tunnel Details page. And I can access this machine with IPv4 through the PPTP VPN tunnel. I just can't get IPv6 to go out.
Here are the settings I have:

And I can't ping6 the tunnel endpoint:

I also tried adding my Lan IP (en0) to gif0
overcompensation:~ root# ifconfig gif0 tunnel 10.69.137.151 209.51.181.2

And adding the PPTP client IP address, but I didn't think this would work because this IP is already in use by ppp0.
overcompensation:~ root# ifconfig gif0 tunnel 184.104.31.139 209.51.181.2

Any suggestions on what to try next would be greatly appreciated.
