SSL VPN with IPv6 Transport

I tried to connect to my asa's outside address via IPv6 AAAA records  using using SSL client  from a dual stacked network using the 2.4.1012 release for windows 64 bit platform.  I have 'A' records with the same name pointing to the v4 address of this same interface. The ASA's log shows the connection attempt being denied over v6 transport.  If I remove the AAAA records from the dns record that points to my ASA it works.  Why is this?

Re: SSL VPN with IPv6 Transport

Which ASA version?

I saw something before about AnyConnect not supporting IPv6

Currently Anyconnect will not connect to ASA over IPv6. You can however use IPv6 address inside the tunnel.
