Can the AnyConnect VPN Client work through an IPsec VPN Client tunnel?
A. This is not officially supported. The reason it cannot work is because both the IPsec VPN Client and the AnyConnect VPN Client are trying to route traffic to their virtual adapters. The IPsec VPN Client is intercepting AnyConnect traffic at the instant messaging (IM) layer. However, it has been retested and appears that it might work with some caveats.
