In this tutorial you will learn How to Configure Unifi UDM PRO DHCP Relay To Use Windows Server DHCP. This will come handy when you want your Windows Server to be the DHCP provider. This tutorial is based on Unifi Controller version 6.5.55.
Let’s get started.
First make sure you are running the latest controller version. At the time of this publication, it is 6.5.55. I will be progressing through this tutorial under the impression you already have a Windows DHCP Server already running. If that is not configured click: How To Install And Configure Windows DHCP Server.
1. Log into your UDM Pro using unifi.ui.com or its IP address.
2. Access the Unifi Controller and click Settings
3. Click on Networks. Now you should be presented with all your current networks maybe even just the Default LAN if your UDM Pro is coming right out of the box
4. Edit your default or primary LAN and give it a name. Afterwards locate and click on the Advanced dropdown.
5. Provide your network domain name. In my case its HDN.local which is short for Home Domain Network, if anyone was wondering.
6. This is important to NOTE, before you even move forward with this you will need to make sure that your UDM Pro has the correct default gateway you want it to have. So, apply that first. Now that you did your due diligence, we can now select DHCP Relay for your Primary Lan.
7. Afterwards click Apply Changes.
8. Now let’s click on Advanced Features.
9. Scroll to the bottom and click on Advanced Gateway Settings.
10. Locate and click on DHCP.
11. Now that you’re in the DHCP utility click the dropdown for DHCP Relay.
12. Type in the IP address of your DHCP server and click Add.
Reboot some of your network equipment and you should now see devices obtaining an address lease from your Windows DHCP Server.
