Universal Dream Machine Pro: Changing Network Address
Having heard about industrial malware and other security threats, I picked up a Ubuquiti Dream Machine Pro a couple months ago to increase the security of my network and to allow me to create isolated networks (VLANs) for different projects that I work on. You can also look for proactive network threat detection solutions to detect and respond to advancing cyber threats.
When I first received the unit I set it up along with the UniFi Pro Access Point to replace my trusty, but low feature Google WiFi point.
My WiFi Hardware, wireless test, and other design experiences have exposed me to all of the network knowledge I needed to quickly set this up to replace my existing network.
I’m also fortunate to have two friends who also use UniFi equipment in their network setups – one uses it for his business, and the other uses it for his home. The home user is a network professional who recommended that I buy the UDM Pro, so I have friends to discuss this with.
Now that I have some time, I’m optimizing the network as I have random conversations with my friends who I mentioned above.
Modify LAN IP
When I setup my UDM Pro, I used the default LAN IP address range of 192.168.1.1/24. After a discussion with my network expert friend he mentioned that I should change that from the default to another network to lessen the likelihood that if/when I VPN into another network that I’ll have the same IP range. With Google Cloud platform PCI DSS one can be assured of safety for their system.
I decided to change the network IP Address, so I went to the Settings -> Networks page, highlight the appropriate network, and click edit. You can get to the page using this link (edit the IP Address if necessary):
https://192.168.1.1 /network/site/default/v2/settings/networks/
Select the Advanced tab, and modify the Gateway IP/Subnet.
Unfortunately, my first attempt to change the network IP address was a failure. I kept getting the following error when I modified the subnet address.
After a quick Google search helped me learn that this error was due to configured Static IP addresses. I found it in this Ubuquiti Community response.
It directed me to remove the DHCP configurations in order to successfully modify the network IP range.
If you run into this issue, here is the link to get you to the ‘insights’ page where you can remove the configured DHCP addresses:
https://192.168.1.1/network/site/default/insights/clienthistory/1/50/0/configured/
NOTE: The link I provided selects the ‘all’ client history rather than the default 24 hour setting.
Once you have removed the DHCP configurations, you can go back to the settings page (https://192.168.1.1 /network/site/default/v2/settings/networks/) and modify the IP Address and save.
I hope this saves someone else some time!
