PROmesh P20 - User Manual 19
The PROmesh P20 supports the application of aggregated network resources, i.e. the logical coupling
of several physical connections to a logical connection. With this, an optimal netload distribution is
enabled for selected connections with high data traffic and the physical bandwidth of a connection is
expanded logically in the event of a high load. To this end, the PROmesh P20 can be configured using
the link aggregation protocol.
2.7.1.2 NAT routing
Industrial networks are characterized by integration of all communication devices within one PLC
domain.
As the meshing of these (sub)networks increase, it becomes increasingly necessary to handle
monitoring and control tasks that are not within the operational level of the automation system.
The basis for achieving these tasks is that a connection has to be established between different address
areas in the Ethernet-based communication. Simultaneously, access to important resources and
network resources within the automation task is to be strictly prevented.
Therefore, the PROmesh P20 has been equipped with complete Layer-3 support, as well as NET
routing functionality with basic firewall properties.
Network devices within the LAN automation environment are thus efficiently protected against access
of network components that are outside of this environment. Simultaneously, a defined gateway
becomes possible through the introduction of NAT rules.
Filtering based on the blacklist procedure therefore only allows connections that have been clearly
defined in advance.
To also support this characteristic physically, access to the automation network is limited to network
components with connection to Port 20 of the PROmesh P20 .
For more characteristics and properties for configuring the NAT functions, refer to Section 3.9 of this
manual.
3 Web application
The PROmesh P20 switches are equipped with a modern web interface by which they can be conveniently
configured from any web browser.
3.1 Preparations
Install the PROmesh P20 switch in the network before you use the web management and make sure that
the PC intended for the configuration of the switches can access the switch via the web browser. Connect
the PC to one of the data ports with a suitable data line (P1-16, G1-G4). The PROmesh P20 and the client
PC to be connected have to be in the same IP address range and IP subnetwork. To this end, you first
have to assign an appropriate IP Address to your PROmesh P20.
