operating system and render your computer inoperable.

2.)Locate and click the following key in the registry:

4.)Type ClientCacheTime, click the REG_DWORD data type, and then click OK.
5.)In the Data box, type a decimal value in milliseconds, and then click OK. E.g., a
value of 1800000 (decimal) corresponds to a time-out of 30 minutes.

IPSec Configuration
The IDU implements Internet Protocol Security (IPSec) in order to access the Internet or
other network at the hub. The IDU and the IPSec server must negotiate and establish a tun-
nel in order for the IDU to transmit and receive traffic data.
The IPSec Configuration page enables you to configure IPSec settings:
• Create an IPSec server table entry (
section 4.2.1)
.
• View or Modify an IPSec server table entry (
section 4.2.2)
.
• Delete an IPSec server table entry (
section 4.2.3)
.
In addition, you can download a new IPSec key using the File Management web page. See
section 2.6.3
