Configuration Guide How to Configure Local DNS Server on Omada Router
Background:
This post provides a configuration guide on configuring the local DNS server in standalone mode.
This Article Applies to:
Omada routers with LAN DNS capability.
Configuration Steps:
1. Log in to your router by 192.168.0.1(default gateway IP).
2. Go to Network > LAN > LAN DNS. Click Add.
2. Create a DNS entry. Note that this DNS entry may apply to a single network or all of your VLAN interfaces.
Verification:
Open Command Prompt:
In this case, we are using .local and .com. You may use other suffixes.
In this case, the DNS server is 192.168.0.1. The resolution is 192.168.0.1. It is displayed as such.
Enter the domain names:
Note:
1. Configuration steps for Controller mode are similar.
2. Please note that this will involve an adapted firmware, not just a controller update. Firmware development is a complex process, and timelines may change. Therefore, we cannot provide a specific release date at this time. Please stay tuned to future firmware release notes for updates.
3. When introducing a feature like this, we typically apply it uniformly across all models to ensure consistency and a seamless user experience.
However, it's essential to acknowledge that hardware limitations may exist, which might prevent us from adding the feature to certain models. In such cases, we cannot provide individual notifications explaining the reason. Please note that we cannot guarantee the fulfillment of all requests, and we must set clear expectations upfront.
4. When the Type is IP/CNAME, wildcard * is supported. For example, "*.
tplink.com" means that all domain names containing ".tplink.com" are supported, but such as "tplink.*.com" or "tplink.com.*” are not supported.
5. Please make sure your DNS server IP is the router's LAN IP. Or this Local DNS server(LAN DNS) configuration is not effective.
6. VPN would be effective for the local DNS configuration. Make sure you have configured the VPN server DNS as the router's LAN IP.

It is really a "half-baked" solution to add just a manual/static DNS entry mechanism to the the Firmware.
ALL other routers with this feature dynamically populate the DNS entries from the DHCP list.
In my use case, as with the majority of others, I am already maintaining a manual DNS list for the LAN elsewhere on the network so this feature is functionally useless.

@Clive_A Sorry, but I'm not quite seeing where to add the manual entries - in the SDN Controller. The example shows how to do it in a non-adopted firewall, but not on the Controller?
Also, is there a way to import a file full of records? Also export a similar list from the Controller?
Thanks!

LAN > LAN DNS.
No. Use CLI.

@Clive_A Thanks! And LAN > LAN DNS makes sense, that's where I'm setting the DNS server (to my gateway). But ... where / how to enter the actual DNS entries then (i.e. my ~ 200 client IP's)?

@Clive_A Will do, but ... from the CLI, it only says my switches are supported, not my gateway? Thanks!

Try the SSH. One thing to notice is that adding entries to LAN DNS might not be available in CLI mode. I have not tested it yet. If that is supported, the easiest way is to use the CLI, which can be added in batch.

@Clive_A OK, let me dig more ;). I tried to ssh into the gateway, but it says that ssh (port 22) is not open. Hmmm. And not sure about the needed CLI command (yet LOL). Thanks!

@Clive_A Sorry, this one is still a bit open :(. A couple questions,
- the CLI does not seem to be available for the gateway / router ... or how to turn it "on" / enable it?
- from the Controller web interface, do I need to add a new LAN DNS ("profile") for every single entry? Thinking there should be multiple within a LAN DNS? Or is this a single entry?
Thanks!

Hi @Clive_A,
based on my observation:
- in source code of Omada router ER605 I can find dnsmasq and unbound
- primary DNS server is unbound
- the default configuration is disabled (recursive search using root hints)
- instead it relies exclusively on forwarders defined in Internet settings - DNS servers of ISP or google, etc....
- that means, if there is no DNS defined in Internet settings, the router will resolbe nothing......
- the dnsmasq is used only as a DHCP server with no connection to unbound
why is the recursive search using root hints disabled? I would very appreciate the configuration option to not rely on forwarders due privacy concerns
(dnsmasq-unbound integration was alread discussed in another thread and even if there are requests from other users (even in this thread), I don't want to re-open this topic again 
)
