Configure the Advanced SSL VPN Client Settings

The advanced SSL VPN client settings let you change the link control protocol (LCP) time-out period, which determines when an SSL VPN connection is terminated after a problem has been detected on a link between the UTM and an SSL VPN client. If an LCP echo request times out three times, that is, three times the request does not receive a corresponding echo reply during the configured LCP time-out period, the SSL VPN connection is terminated.

The default LCP time-out period is 60 seconds, which means that if echo reply requests time out three times, the SSL VPN connection is terminated after 180 seconds. If the link comes back up within 180 seconds, the SSL VPN connection is automatically reestablished.

If the UTM is many hops away from SSL VPN clients, or if the intermediate connection between the UTM and SSL VPN clients is unreliable, you might want to increase the LCP time-out period to more than 60 seconds.

To change the LCP time-out:

1.Select VPN > SSL VPN > SSL VPN Client. The SSL VPN Client screen displays (see Figure 219 on page 366).

2.Click the Advanced option arrow in the upper right of the SSL VPN Client screen. The SSL VPN Advanced screen displays:

Figure 220.

3.In the LCP Timeout field, enter a time in seconds. The default value is 60 seconds.

WARNING:

When you click Apply, all SSL VPN connections are terminated.

Users need to manually reestablish the SSL VPN connections.

4.Click Apply to save your settings.
