Secure IPsec tunnel between two
VPN Gateways (or cluster of VPN
Gateways) or similar devices. The
tunnel is automatically established
when traffic destined for specific
remote networks is detected, provided
traffic was initiated from a network
allowed to send traffic through the
tunnel. BO tunnels can e.g. be set up
between a main office and a branch
office.
A trusted third-party organization
or company that issues digital
certificates. The role of the CA in this
process is to guarantee that the entity
granted the unique certificate is, in
fact, who he or she claims to be.
The text-based interface on the
VPN Gateway, presented to the
user after having logged in. The CLI
can be accessed through a console
connection or remote connection
(Telnet or SSH). The CLI is used for
collecting information and configuring
the VPN Gateway.
A cluster is a group of VPN Gateways
that share the same configuration
parameters. There can be more than
one NVG cluster in the network, each
with its own set of parameters and
services to be used with different
real servers. Every cluster has a
Management IP address (MIP), which
is an IP alias to one of the master VPN
Gateways in the cluster.
A connection to the VPN Gateway
established through the console port.
A list containing the serial numbers of
revoked client certificates. Each CA
issues and maintains their own CRLs.
If you generate client certificates on
the VPN Gateway, you can also create
your own CRL.
A request for a digital certificate,
sent to a CA. On the VPN Gateway,
you can generate a CSR from the
command line interface by using the
request command.
