The Networks page allows you to define Network Descriptors.
What is a Network
Descriptor?
The concept of Network Descriptors is introduced for the first time in the
SpeedTouch™ R5.3. 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.
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 Profile. A Connection Profile refers to a Network Descriptor by its
symbolic name.
Network name Internal symbolic name to identify the Network Descriptor.
Type of network and IP
address
The Type and IP parameters locate the network in the IP address space. In the IP
field, you enter a value corresponding to the network Type.
Type IP
Valid network types are: Keyword: Examples:
a single IP address address
10.0.0.15
a single IP subnet subnet
10.0.0.0/24
a contiguous IP address range range
10.0.0.5-10.0.0.56
10.0.0.[5-56]
