Local Networks

Configure the LAN interface to set up local intranet networks.

Do not stop or delete the LAN (bar-lan) interface, which is the DHCP server of local networks and the cornerstone of Ethernet and Wi-Fi functions.

i. Configure IP Pool

To modify the DHCP configuration, you need to log in to the router admin, go to Network > Interfaces on the top menu. Click Edit on the row of LAN (local area network).

Configuration > General

In the section of Common Configuration > General Setup, you can modify the router IP address, netmask, gateway address, broadcast address, and DNS servers.




IPv4 address

IP address that the router uses on the LAN network

IPv4 netmask

Netmask is used to define how “large” the LAN network is

IPv4 broadcast


Broadcast is used by DHCP clients to find and send requests to their respective servers

DHCP Server > General

Scroll down and find the section of DHCP server > General Setup, you can modify the DHCP IP pool and DHCP lease period.

The DHCP server can automatically configure the TCP/IP settings of connected devices and lease out an IP address from the available IP pool.

To disable the DHCP server, you can select the checkbox of Ignore interface.






The start of the DHCP IP pool.

For example, if the router’s LAN IP is and the netmask is, a valid IP address should be in the range of […]

* is a special unavailable address.



Define the IP addresses the DHCP server can lease out.

Continuing from the above example: if the start address is and the server can lease out 150, available addresses will be from to

Lease time

12 hours

The duration of an IP lease. Leased-out addresses will expire after the specified period, and you have to request a new DHCP lease.

If the device stays connected, its lease will be renewed after half of the specified amount of time passes.

For example, if the lease time is 12 hours, then every 6 hours, the device will send a request to the DHCP server asking to renew its lease.

The lease time can be set in hours (h) or minutes (m). The minimum time that can be specified is 2min (2m).

DHCP Server > Advanced

Under the tab of Advanced Settings, you can set up more configurations on the DHCP server.




Dynamic DHCP


Enables dynamic allocation of client addresses. If disable it, you have to input static IP address on the connected devices.



The DHCP force function ensures that the router will always start its DHCP server, even if there is another DHCP server already running in the router’s network.

*** When connecting the router to another router via LAN cable, the outdoor router will turn to AP mode and obtain the IP address assigned from another router. You will no longer be able to access the router at

IPv4 Netmask


Overrides the LAN netmask, thus making the DHCP server think it’s serving a larger or smaller network than it actually is.

DHCP Options


For example, with ‘26,1470’ or ‘option:mtu, 1470’ you can assign an MTU value per DHCP. You can add more options by clicking the plus symbol (Services sms gateway auto-reply plus symbol.PNG) located next to the field.

ii. Physical LAN Interface

There are five physical RJ45 ports on the EZR24 router. LAN Ethernet is bound to the logical port eth0.1 which includes physical LAN 1~4 ports.

iii. DHCP Leases

To check the active DHCP clients, you need to log in to the router admin, go to Network > DHCP & DNS, scroll down and find the section of Active DHCP Leases.

Static Leases

Static IP leases reserve specific IP addresses to particular devices by binding them to their MAC address. It’s useful when having a stationary device connected to the network that needs to reach frequently, such as NAS, printer, camera, etc.

Field Name

Default Value




A custom name that describe be linked device

MAC Address


MAC address of the linked device

IPv4 Address


The desirable IP address that reserved for the specified device
