How to Configure DHCP Server on Omada Gateway

This article introduces how to configure the DHCP function on the Omada Gateway in both Standalone and Controller modes.

What is a DHCP Server?

When creating a LAN Network, the Omada Gateway can enable the DHCP Server service to assign IP addresses and other network configuration parameters, such as subnet mask, gateway address, and DNS server addresses, to connected clients.

How to Configure the DHCP Server in Standalone Mode

In standalone mode, you can configure the DHCP Server service when you click Add to add an L3 network interface in Network > LAN > Network List.

Step1:

The DHCP Server runs on the corresponding LAN Network, so you need to complete the basic configuration of the LAN Network first.

IP Address: The address will be used for the DHCP Server.

Vlan: Configure the corresponding VLAN, and the interaction between the DHCP Server and the client will be performed in this VLAN.

Step2:

Configure DHCP Server settings.

Starting IP Address/Ending IP Address: Configure the DHCP address pool range, which needs to be in the same subnet as the DHCP Server.

Lease Time: Configure the lease duration.

Default Gateway: Configure the client's gateway information.

Primary DNS/Secondary DNS: Assign DNS Servers to the client.

DHCP options: You can configure some common option fields in Advanced Settings, or click Add to add custom options.

How to Configure the DHCP Server in Controller Mode

In Controller mode, you can configure the DHCP Server service when you click Create New LAN to create an L3 network interface in Setting > Wired Networks > LAN > Networks.

The configuration items are the same as in standalone mode.

Note:

1. The DHCP Server’s assigned IP range corresponds to the LAN Network subnet.

2. If the Default Gateway is not configured, the system will use the DHCP Server’s address (which is also the LAN interface address) as the gateway by default.

3. If Primary DNS/Secondary DNS are not configured, the system will use the DHCP Server's address (which is also the LAN interface address) as the DNS server, and the Gateway will perform DNS proxy.
