Unable to share IPV6 Internet connection with other computer by network-manager

[Qian Hong]

Binary package hint: network-manager

On Ubuntu 9.10 ,we can easily sharing IPV4 Internet Connection with other computers by following steps:
1.Right click Network-Manager-Applet.
2.Click the "Edit Connection" menu.
3. Add a new connection.
4.Edit to the "IPV4" tab.
5.Change "Method" to "Sharing with other computers".
6.Apply & Connect.

Howerver,when I try to edit the "IPV6" tab instead of the "IPV4"tab,I found it doesn't work,the option "Sharing with other computers" is disable in the IPV6 tab.I wonder how to share ipv6 Internet connection by network-manager ?
I'm not sure wheather this is a bug ,if not , anyone could tell me how to share ipv6 connection by network-manager or any other GUI applications?

Many thanks!
