2.2.2 The ‘IPSec’ submenu
In this submenu, you may configure IPSec encryption (IP Security). IPSec is a set of protocols
used for protection of data transmitted via Internet Protocol that enables authentication, integrity
check and/or encryption of IP packets. IPsec also includes secure Internet Key Exchange protocols.
IPSec settings:
-
IPSec enable
IPSec enable
– permit to use IPSec protocol for data encryption;
-
Name of service
– service selection where encryption via IPSec protocol will be used;
-
Local IP address
– the device address for operation via IPSec protocol;
-
Local subnet
in cooperation with
Local netmask
determine local subnet for creation
network-to-network or network-to-point topology;
-
Remote subnet
in cooperation with
Remote netmask
determine address of remote
subnet for connection with using encryption via IPSec protocol. If the mask value is
255.255.255.255, communication is performed with a single host. Mask that differs from
255.255.255.255 allows defining a whole subnet. Thus, functionality of the device allows
