4.6 Network Descriptor
What is ... The concept of Network Descriptors is introduced for the first time in the
SpeedTouch™ R5.3.0. Not only the classical idea of an IP network or subnet is
comprised in this concept, but also the protocol and port number of the messages
can be specified, such that access to the VPN can be restricted to certain hosts,
protocols and port numbers.
Both the origin and destination traffic policies are expressed by referring to a
Network Descriptor. To this end, a symbolic name is attributed to a Network
Descriptor.
The definition of relevant Network Descriptors is linked with the topology of the
VPN that is constructed with the IPSec configuration. The Network Descriptors
determine the type of messages that will trigger the IPSec module.
The Network Descriptor parameters are explained in section 4.6.1.
How is it used Network Descriptors can be used to express the origin and destination networks for
an IPSec Connection. In case a static IPSec policy is used, the local and remote
private networks are described by referring to a Network Descriptor. In this case,
relevant Network Descriptors have to be created prior to the definition of a
Connection. The Connection refers to the Network Descriptors by their symbolic
name.
