That won't work, either. Cisco uses some extensions to IPsec that aren't supported in the native MacOS VPN client.

It might work to connect, as OS X has specific "Cisco IPSec" as well as normal L2TP over IPSec. Works fine to connect to my work, however the OS X client also enforces the same split-tunneling restriction the Cisco client does.
