LAN Settings

Manage your local network address, DHCP address pool, lease time and static IP assignments.

Quick Navigation

1. LAN Settings Overview

LAN Settings controls how local IP addresses are assigned inside your Mercku network.

LAN IP

Defines the local network address used by the router.

DHCP IP Pool

Defines the range of IP addresses that the router can automatically assign to client devices.

Static DHCP Lease

Bind a device MAC address to a specific local IP address.

Before Changing LAN Settings

Changing local network settings can affect how devices receive IP addresses. Record your current settings before making changes.

3. DHCP Settings

DHCP automatically provides local network information to devices connected to your router.

LAN Network Information

Configure the router’s local network information.

IP Start / IP End

Define the beginning and end of the DHCP address pool.

Lease Time

Controls how long a DHCP address is assigned before it is renewed.

DHCP Operating Modes

The Mercku OS configuration supports DHCP server, DHCP client and DHCP-disabled network modes. The options shown in Router Web depend on the current product and network mode.

4. Static DHCP Lease

Static DHCP Lease is used to keep the same local IP address for a specific device.

How It Works

The router binds a device’s MAC address to a selected IP address.

When to Use It

A fixed local IP can be useful for devices that need a consistent address, such as local servers or devices used with other advanced network rules.

Check Your Address Plan

Use an IP address that belongs to the correct LAN network and does not conflict with another device.
