Perle Systems SCS, STS manual Shared Secret Field Description

VPN

Remote Next Hop	The IP address of the router/gateway that will forward data packets to the
	IOLAN (if required). The router/gateway must reside on the same subnet at the
	remote VPN.
	Field Format: IPv4 or IPv6 address
Remote	The IP address of a specific host or the network address that the IOLAN will
Host/Network	provide a VPN connection to. If the IPsec tunnel is listening for connections
Address	(Boot Action set to Add), and the field value is left at 0.0.0.0, any VPN peer
	with a private remote network/host that conforms to RFC 1918 (10.0.0.0/8,
	172.16.0.0./12, 192.168.0.0/16) will be allowed to use this tunnel if it
	successfully authenticates.
	Field Format: IPv4 or IPv6 address
Remote IPv4	The subnet mask of the remote IPv4 network. Keep the default value when you
Subnet Mask	are configuring a host-to-host VPN connection.
	Default: 255.255.255.255

Remote IPv6 Prefix The prefix bits of the remote IPv6 network. Keep the default value when you

Bits	are configuring a host-to-host VPN connection.
	Default: 0
Boot Action	Determines the state of the VPN network when the IOLAN is booted.
	Data Options:
	z Start—Starts the VPN network, initiating communication to the remote
	VPN.
	z Add—Adds the VPN network, but doesn’t initiate a connection to the
	remote VPN.
	z Ignore—Maintains the VPN network configuration, but the VPN network
	is not started and cannot be started through the IPsec command option.
	When defining peer VPN gateways, one side should be defined as Start
	(initiate) and the other as Add (listen). It is invalid to define both gateways as
	Add. VPN connection time can take longer when both gateways are set to
	Start, as both sides will attempt to initiate the same VPN connection.
	Default: Start

Shared Secret Field Description

When the Authentication Method is set to Shared Secret, you can enter a secret that applies to all VPN tunnels (both the IPsec and L2TP/IPsec protocols) to successfully authenticate and create a valid connection.

Configure the following parameter:

Secret	When the Authentication Method is set to Shared Secret, enter the
	case-sensitive secret word.This applies to all VPN tunnels (IPsec and
	L2TP/IPsec).
	Field Format: Maximum of 16 characters, spaces not allowed
