OpenVPN Client-to-Site Settings
Use the "Client-to-Site" settings to provide VPN access to remote client computers via
the OpenVPN protocol.
Under "VPN > OpenVPN > Client-to-Site", you can add or edit an existing OpenVPN
C2S connection.
The "Client-to-Site" settings allow you to configure the following elements:
Field Description
"On" / "Off" A slider switch indicates whether the OpenVPN C2S connection is active
( "On" ) or inactive ( "Off" ). By clicking the slider switch, you can toggle the
state of the connection. A new connection is enabled by default.
"Show on Desktop" This checkbox is pre-selected by default. You can clear the checkbox if you do
not want the OpenVPN C2S connection to be displayed as a node in the net-
work overview on the desktop.
"Color" Select the color to be used for this object on the desktop. The color is set to
black by default.
"Name" Enter a unique name for the connection. It must consist of a minimum of three
lowercase alphanumeric characters.
"Access Zone" From the drop-down list, select the zone which is directly accessible to the
remote site.
"Use Compression" Optional: Select this checkbox to activate LZO (Lempel-Ziv-Oberhumer, a loss-
less data compression algorithm) compression.
"Use TCP Protocol" Optional: Select this checkbox to use the TCP protocol. Otherwise UDP is
used. TCP is not recommended.

tions by entering a value from 1 to 65535.
Note: The same port number must be specified in the client software.
"Key Renegotiation" An OpenVPN connection renews the session key while the connection is estab-
lished to increase security. Specify this rekeying interval (in seconds).
"Certificate" Select the server certificate for OpenVPN connections from the drop-down list.
"Certificate Password" Optional: Enter the "PK Password" of the VPN certificate if you decide to secure
the private key. For more information, see Chapter 3.4.8.1, "Certificates",
on page 122.

connection. The following options are available:
