MacOS pptp client + IPv6

[Jared Mauch]

Anyone gotten the MacOS PPTP/VPN client to obtain an IPv6 address?  I'm using a Cisco router on the other end, and am looking for anything obvious i'm missing.  It appears to be sending the traffic out the virtual-access interface just fine, but I'm not seeing an IPv6 address on the ppp0 interface.
