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

on keeping alive to have the ZyXEL Device
renegotiate an IPSec SA when the SA lifetime expires, even if there is no traffic.
