On the UC520 with both IOS 15.0(1)XA1 and XA1a, the VPN client seems to be broken? The moment I upgrade from 12.4(24)YB4 to 15.0, the VPN client can connect but there is no data transfer. If I downgrade to 12.4(24) again everything is fine. I really want to upgrade to IOS 15 to fix a number of other bugs that are annoying me but I can't do so if the VPN client does not work. AnyConnect still works however this gives us major issues for users with IP Communicator.
Can anyone confirm if this is a bug? I can't find any mention of it in the bug toolkit.
