transmitted, it stays completely unknown to everyone, thus the system remains safe. Even if someone gets the public key, decryption cannot be

possible without the private key. Quadro generates such a pair of keys automatically when it is set up. The user cannot see the private key, but must

know the public key because their IPSec connection partner will need it.

Please Note: A pair of keys will always be generated, a public one and a private one. The previously generated pair of keys will become invalid as

well as all existing IPSec connections that use RSA keying.

The IPSec Configuration link refers to the IPSec Connection Settings page. This page provides an overview of all existing IPSec connections

characterized by their Connection Name, the Remote Gateway (the IP address or the hostname of the IPSec connection partner), the State of the

IPSec connection (Stopped, Connecting, Activated, Waiting or Connected) and the dedicated Keying Type (the encryption type). The content of the

table can be sorted in ascending or descending order by clicking on the header of the respective column. There is a checkbox for every IPSec

connection to select it for further editing.

Start activates the connection establishment of the selected

IPSec connection. The State of the IPSec connection will

change into “Connected” or “Activated” depending on the IPSec

connection type. If no record is selected, the error message

“One Record should be selected” appears.

Attention: It is not recommended to simultaneously start a

static and a dynamic connection configured to use the same

secret key. A dynamic connection may capture the static

connection peer and vice versa, depending on which connection

established first.

Stop disconnects the selected IPSec connection. The state of

the IPSec connection will change into “Stopped”. If no record is

selected, the error message “One Record should be selected”

will appear. More than one record may be selected at a time to

be stopped.

Add leads to the Add IPSec Connection wizard where a new IPSec connection can be defined and specified. The wizard provides several pages.

Edit leads to a set of IPSec Connection Properties pages to modify the parameters of the selected IPSec connection. The page includes the same

components as the Add IPSec Connection page. To operate with Edit, only one record may be selected, otherwise an error message “One row

must be selected” appears.

Restart all Connections restarts all active IPSec connections. The State of these IPSec connections will turn into Connected or Activated if the

restart procedure has been successfully completed.

RSA Key Management leads to the RSA Key Management page to see the current RSA key, to generate a new one and to send it to the peer via

e-mail.

The first IPSec Connection Wizard page Add IPSec

Connection has the Connection Name text field that requires a

new mandatory IPSec connection name. If the text field is not

filled in, the error message otherwise an error will occur “Error:

Incorrect connection name” will appear.

Please Note: The input in the Connection Name field should

only be in Latin characters, otherwise an error occurs and IPSec

connection cannot be created.

The Peer type drop down list is used to choose the remote

machine type for the IPSec Connection to be established. If the

list does not include the required type of machine, choose

Other.

The VPN Network Topology drop down list allows you to select

the location of the peers participating to the VPN connection.

The following options are present in the list:

• Quadro<>Peer – direct connection between Quadro and a

peer.

• Quadro<>[Internet]<>Peer – connection between Quadro

and peer over Internet.

• Quadro<>NAT<>[Internet]<>Peer – connection between

Quadro and peer over Internet through Quadro provider’s

NAT.

• Quadro<>[Internet]<>NAT<>Peer – connection between

Quadro and peer over Internet through peer provider’s

NAT.

The second page of the IPSec Connection Wizard, IPSec Connection Properties serves to specify the members of the IPSec Connection and to

set the basic parameters for encryption.

A group of radio buttons are used with Dynamic IP/Road Warrior and Static IP/ Remote Gateway to select if the remote Quadro (or another VPN

gateway device) is connected to the Internet with a dynamic IP address and is acting as a Road Warrior, or is connected to the Internet with a fixed

IP address and is acting as a VPN Gateway.
