VPN

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

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

Host/Network

Address

The IP address of a specific host or the network address that the IOLAN will

provide a VPN connection to. If the IPsec tunnel is listening for connections

(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 confo rm s 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

Subnet Mask The subnet mask of the remote IPv4 network. Keep the default value when you

are configuring a host-to-host VPN connection.

Default: 255.255.255.255

Remote IPv6 Prefix

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

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:

zStart—Starts the VPN network, initiating communication to the remote

VPN.

zAdd—Adds the VPN network, but doesn’t initiate a connection to the

remote VPN.

zIgnore—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 shou ld be defined as Start

(initiate) and the other as Add (listen). It is invalid to define both gat e ways as

Add. VPN connection time can take longer when both gateways are set to

Start, as both side s will attempt to initiate the same VPN connectio n.

Default: Sta rt

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
