LAN DNS entries from DHCP Leases

Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.3.3

Model: ER605-M2  

Hardware Version: V2

Firmware Version: 2.3.3

 

Improve the use of the LAN-DNS by automatically or easy manual import of DHCP-Leases into the LAN-DNS

 

User-Story: 

I have around 200 Network-Devices in my Home-Lab local Lan and i want to use the Omada DHCP Service for the network.
It would be great to get all Leases fixed or temporary to show up in a local LAN-DNS.

 

Why?

This is a Standard-Feature of other Vendors (Cisco, Unify...)

 

Proposed Solution:

Activate DNS-Entry and Alias in the Client-Config: 

The Mockup shows

  • additional checkbox to enable the LAN-DNS-Entry for the Client
  • A Text-Field for a List of Domains the Client should be Associated with
  • A Text-Field for a List of Alias-Names in addition to the Client-Name

 

Why in the Clients-Config, not in the DHCP-Config?

  • Put into Clients-Config so it also available for Fixed IPs that have not been assigned by the DHCP
  • DHCP-Clients - update the DNS-Entries every time the Lease is renewed

Hi @tpriko,

 

I've tried to propose this back in June 2025, but the static entries only were marked as expected behavior..... see my old post here.

  @ZoloNN i talked to the business-sales and they understood perfectly fine, that this would be a feature that would push the value of the devices and give them an edge on other vendors... but...

 

This is why i made a Feature Request and hope that the Developers will see it. 
There is actually a DIY solution for the self deployed omada-controller.

 

And since on a low level it is only a matter of synchronizing text-files this should not be hard to implement.

Hi @tpriko,

 

as I wrote in my original post, this is only a matter of changing two configuration files in the gateway which is described in following OpenWRT README. No change to the firmware build itself is necessary.
