    There is a parameter that can be set in the Cisco VPN client config file
    ".pcf" to allow access to local RFC 1918 networks, however when I tried this
    it did not work however it does work with the Window$ Cisco client. Maybe the
    latest V4 client (I think this is now available forlinux) will correct this
    apparent bug.
