Configuring Teleworker VPN Client
Cisco ISA500 Series Integrated Security Appliances Administration Guide 368

This section describes how to enable the Teleworker VPN Client feature, configure
the Auto Initiation Retry settings, and manually connect or disconnect the VPN
connections.
STEP 1 Click VPN > Teleworker VPN Client.
STEP 2 Enter the following information:
•Tel ewo rke r V PN C li ent : Click On to enable the Teleworker VPN Client
feature and hence set the security appliance as a Cisco VPN hardware
client, or click Off to disable it.
NOTE: Enabling the Teleworker VPN Client feature will disable the
Site-to-Site VPN and IPsec Remote Access features and terminate their
connected VPN sessions.
•Auto Initiation Retry: Click On to enable the Auto Initiation Retry feature, or
click Off to disable it.
When you enable Auto Initiation Retry, the security appliance (set as the
Cisco VPN hardware client) first initiates the VPN connection to the primary
server. If there is no response from the primary server after the timeout that
you set in the Retry Interval field, the security appliance then re-initiates the
VPN connection to the primary server. This continues for the number of times
that you set in the Retry Limit field (or until the primary server is conne cted).
If the primary server cannot be connected after the specified number of
times, the security appliance tries to re-initiate the VPN connection to the
backup servers by following the specified timeout and retry times. If all three
backup servers cannot be connected, repeat the re-initiation process again
and again until an IPsec VPN server can be connected.
When you disable Auto Initiation Retry, the security appliance first initiates
the VPN connection to the primary server. If there is no response from the
primary server in 120 seconds, the security appliance then re-initiates the
VPN connection to the backup servers. If all three backup servers cannot be
connected, repeat the re-initiation process again and again until an IPsec
VPN server can be connected.
•Retry Interval: Specify how often, in seconds, that the security appliance
re-initiates the VPN connection to the primary server and the back servers.
The default value is 120 seconds.
•Retry Limit: Enter the number of times that the security appliance will retr y
a VPN connection initiation. The default value is 2.
