[c-nsp] ASA5510 and Access to a local Network

[Stephane MAGAND]

Hi

i am search a information:

I use two cisco ASA5510 with cisco VPN client. I want that when a user
are connected at the asa in Ipsec, the local network of the user are
"disconnected"
all traffic are sent into the tunnel.

I see the option into the Cisco Vpn client software, but that's don't
work. I see in
the Help that for force the "Local Lan disconnect", he require that
this option are On
on the Cisco ASA

Do you know where is this option on the ASA ?

Thanks for your help
Stephane
