IP Routes Configuration
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

Adding a new IP Route
To add a new route, enter the details using the table below for reference. Click Add IP route to 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. The MCU can support up to 128 routes in total.

specify the IP address as 192.168.4.128 and
the mask length as 25, to indicate that all but
the last seven bits address are fixed.
