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.
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
.
DHCP Server > Advanced
Under the tab of Advanced Settings
, you can set up more configurations on the DHCP server.
ii. Physical LAN Interface
There are two physical RJ45 ports on the EZR23 router. LAN Ethernet is bind with physical port eth1
by default, which also takes the DC power from PoE adapter.
You can also bind another RJ45 port eth0
to the LAN interface, which is bind to the WAN interface by default. If you switch the LAN interface from eth0
to eth1
, the PoE adapter will lose the Ethernet function on it's LAN port.
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 is used to 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.
