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
Section 18.6 on page 279 on keep alive to have the ZyXEL
Device renegotiate an IPSec SA when the SA lifetime expires, even if there is no traffic.
