IKEv1

Setting	Value(s) *=default	Description

Setting	Value(s) *=default	Description
Timeout	30	The maximum period to wait until the request for IPsec tunnel connection establishment must be approved by the remote peer.
Tunnel check interval [s]	30	The interval between queries for a valid exchange that is assignable to an IPsec tunnel.
Dead Peer Detection Interval [s]	5	Tunnels can be configured to be Active or Passive. An active tunnel is capable of establishing a connection while a passive tunnel is waiting for a connection request. This parameter sets the interval between keep-alive checks on the remote peer.
IKEv1 Log Class	ALL*	The debug log class of IKEv2. Do not select a log class different than ALL if the log is not required for solving issues.
IKEv1 Log Level	0*	The debug log level of IKE. The debug log may be very “noisy.” Do not select a log level greater than 0 if the log is not required for solving an issue.
Pre-shared key (PSK)	-	Holds the pre-shared IKE key.

IKEv2

Setting	Value(s) *=default	Description

Setting	Value(s) *=default	Description
Start IKEv2	Selected* Deselected	If selected, IKEv2 will be used. If deselected, IKEv2 will be disabled and some additional memory will be saved.
IKEv2 Make Before Break	Selected Deselected	Selecting this option creates a duplicate of the IKE and all IPsec SAs, and the deletes the old ones. This setting requires that both peers can handle overlapping SAs.
IKEv2 Log Class	All*	The debug log class of IKEv2. Do not select a log class different than ALL if the log is not required for solving issues.
IKEv2 Log Level	0	The debug log level of IKEv2. Do not select a log level greater than 0 if the log is not required for solving an issue.
IKEv2 Suppress Network Change Events	Selected Deselected*	This is an advanced setting. If selected, network interface/address/route changes which may cause an automatic reconnect of the VPN tunnel will be ignored. This parameter becomes active after a restart of the IKEv2 daemon. Restart the VPN service or execute `ipsec restart` in a shell.
