14.16 SA Monitor
In the web configurator, click VPN and the SA Monitor tab. Use this screen to display and manage your
active VPN connection.
A Security Association (SA) is the group of security settings related to a specific VPN tunnel. This screen
displays the active VPN connection. Use Refresh to display the active VPN connection. This screen is read-
only. The following table describes the fields in this tab.
When there is outbound traffic but no inbound traffic, the SA times out
automatically after two minutes. A tunnel with no outbound or inbound traffic is
"idle" and does not timeout until the SA lifetime period expires. See the section on
keep alive to have the ZyWALL renegotiate an IPSec SA when the SA lifetime
expires, even if there is no traffic.
