Industrial router IPL-E User guide ref. 9015909-03 Page 51

When a frame is addressed to the IPL-E router with a particular

configured port, it is transferred to a particular device connected to the

LAN interface.

Example :

Let us suppose the PC named “W1” of the WAN network has to send

frames to the device PLC1 of the LAN network

Suppose moreover that the addresses of the LAN network cannot be used

on the WAN network for any reason.

The solution can be to use the Port forwarding function :

When W1 needs to transmit frames to PLC1, it addresses the frames to

the IPL-E router on a chosen and agreed port.

The router checks the frame, replaces the destination address by the Ip

address of the device on the LAN interface, and eventually changes the

port number.

The port forwarding rule will be
