</tbody></table><p><b>dwIdleTimeout (4 bytes): </b>Duration, in seconds,
after which the connection will be disconnected if there is no traffic. This
value MUST be between 300 and 17,279,999.</p><p><b>dwNetworkBlackoutTime (4 bytes): </b>Retransmission
timeout, in seconds, for IKEv2 Request packets [RFC4306]. IKEv2 expects a
