In this section you can control how IP packets should be directed out of the MCU. You should only change this configuration if you have a good understanding of the topology of the network(s) to which the MCU is connected.
Configuration of routes is divided into two sections: addition of new routes, and the display and removal of existing routes.
To add a new route, first enter the details using the table below for reference. When you are satisfied with the details
entered, clickto make the addition. If the route already exists, or aliases (overlaps) an existing route, you will be prompted to correct the problem and try again.

Configured routes are listed below the Add IP route controls. For each route, the following details are shown:
The IP address pattern and mask
Where matching packets will be routed, with the possibilities being:
oPort A - meaning the default gateway configured for Port A o Port B - meaning the default gateway configured for Port B
o IP address - a specific address has been chosen
Whether the route has been configured automatically as a consequence of other settings, or added by the user as described above.
