I want to use IPv6 over RA VPN using AnyConnect client from Windows XP SP3. But connection is unsuccessful with error message 'The VPN client was unable to successfully verify the IP forwarding table modifications'.
I know there was such bug in AnyConnect 2.4 client, but according to release notes, in 2.5 it is corrected.
I use last AnyConnect 2.5.0217 and ASA5520 with 8.2(1) software.
Thanks for any help.
