Local Networks
Configure the LAN interface to set up local intranet networks.
Do not stop or delete the LAN (bar-lan) interface 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
192.168.20.1
IP address that the router uses on the LAN network
IPv4 netmask
255.255.255.0
Netmask is used to define how “large” the LAN network is.
IPv4 broadcast
N/A
DHCP clients use broadcast 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 connected devices' TCP/IP settings and lease out an IP address from the available IP pool.
To disable the DHCP server, you can select the checkbox of Ignore interface.
Start
100
The start of the DHCP IP pool.
For example, if the router’s LAN IP is 192.168.20.1 and the netmask is 255.255.255.0, a valid IP address should be in the range of [192.168.20.0…192.168.30.254]
* 192.168.20.255 is a particular unavailable address.
Limit
150
Define the IP addresses the DHCP server can lease out.
Continuing from the above example, if the start address is 192.168.20.100 and the server can lease out 150, available addresses will be from 192.168.20.100 to 192.168.20.249.
Lease time
12 hours
The duration of an IP lease. Leased-out addresses will expire after the specified period, and you must 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.
Field
Default
Description
Dynamic DHCP
Enable
Enables dynamic allocation of client addresses. If you disable it, you must input a static IP address on the connected devices.
Force
Disable
The DHCP force function ensures that the router will always start its DHCP server, even if another DHCP server is 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 192.168.20.1.
IPv4 Netmask
NA
Overrides the LAN netmask, thus making the DHCP server think it’s serving a larger or smaller network than it is.
DHCP Options
NA
For example, you can assign an MTU value per DHCP with ‘26,1470’ or ‘option:mtu, 1470’. 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 4G 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 be reached frequently, such as a NAS, printer, camera, etc.
Hostname
NA
A custom name that describe be linked device
MAC Address
NA
MAC address of the linked device
IPv4 Address
NA
The desirable IP address that reserved for the specified device
