5.8 VPN Configuration
The RLXIC-EV can act as a Virtual Private Network (VPN) client, providing
enterprise VPN access to any device connected to the RLXIC-EV even when a
device has no VPN client capability on its own. The RLXIC-EV supports two
tunneling protocols, IPSec and GRE. Both can be used at the same time.
5.8.1 IPSec
The IP protocol that drives the Internet is inherently insecure. Internet Protocol
Security (IPSec), which is a standards-based protocol, secures communications
of IP packets over public networks.
IPSec is a common network layer security control and is used to create a virtual
private network (VPN).
The advantages of using IPSec or GRE feature includes:
 Data Protection: Data Content Confidentiality allows users to protect their
data from any unauthorized view, because the data is encrypted (encryption
algorithms are used).
 Access Control: Access Control implies a security service that prevents
unauthorized use of a Security Gateway, a network behind a gateway or
bandwidth on that network.
 Data Origin Authentication: Data Origin Authentication verifies the actual
sender, thus eliminating the possibility of forging the actual sender's
identification by a third party.
 Data Integrity: Data Integrity Authentication allows both ends of the
communication channel to confirm that the original data sent has been
received as transmitted, without being tampered with in transit. This is
achieved by using authentication algorithms and their outputs.
