Virtual Service IPv6 to IPv4 and IPv4 to IPv4

Hi,
to ease migration of IPv4 to IPv6 it would be good to be able to connect to a VS with IPv6 while the RS still have IPv4.

So it should be possible to support the following at the same time:

Client -> VS (IPv6) -> real server (IPv4)
Client -> VS (IPv4) -> real server (IPv4)

Thanks
