Chapter69 General VPN Setup
Configuring AnyConnect VPN Client Connections
Note If you disable network extension mode, the default setting, the hardware client can connect to
this ASA in PAT mode only. If you disallow network extension mode here, be careful to
configure all hardware clients in a group for PAT mode. If a hardware client is configured to use
Network Extension Mode and the ASA to which it connects disables Network Extension Mode,
the hardware client attempts to connect every 4 seconds, and every attempt is rejected. In this
situation, the hardware client puts an unnecessary processing load on the ASA to which it
connects; large numbers of hardware clients that are misconfigured in this way reduces the
ability of the security appliance to provide service.

Configuring AnyConnect VPN Client Connections

administrators to install and configure clients on remote computers.
