MGate Configuration

...

Moxa provide a Windows based utility that can be used to connect to the MGate and aid in configuring the unit. But the MGate also provides a native web UI that provides the same functionality from any operating system. Out of the box the MGate will have the following default TCP/IP address and default Account and Passwords:

Temporarily set your computer’s Ethernet domain to the 192.168.127.xxx domain. Once you have done that you should be able to , open a web browser and then browse to http://192.168.127.254. That should will result in the following web page to appearbeing displayed:

After you enter the default admin/moxa credentials you will be prompted to enter a new password.

Setting a Static IP Address

Once you have logged into the MGate unit, navigate to the “Network Parameter” tab within the web UI. The MGate unit provides for both DCHP as well as STATIC IP settings. Because we want the MGate to reliably appear at a known IP address after things like power outages and resets, it is best to configure the device with a known STATIC IP address.

• Under the “IP Configuration” drop down in the Web UI, select “Static”.
• Enter a Static IP address that makes sense in your network topology. In this example, we have used 192.168.1.96

• Set the Netmask to what makes sense in your network topology (typically this will be a 255.255.255.0 setting)
• Finally, setup a Gateway IP address. Note, in typical use cases routing thru a Gateway will not be used.
• The DNS1 entry can default to the Gateway IP set above in most use cases.
• Once all of the entries have been made, click on the “Submit” button to activate these settings.
