4.5 Local Networks

The local network settings on EZR33L router.
After log in to the router admin panel, go to "Network > Interfaces" to view and manage the network interfaces. The local network is handling by LAN and WAN interfaces.
  • The color on the interface is not corresponding to its connection status.
  • Rx/Tx indicates the real-time data stream instead of the speed.
EZR33L Router - Interface Overview & LAN Settings

1 LAN (bar-lan)

The LAN interface is controlling the local intranet network. It is bound to the physical eth1 PoE & LAN port. Click the "Edit" button on the "LAN" interface to configure the intranet network, including the IP pool.

Router IP

Change the "IPv4 address" on the "Common Configuration" to modify the router's IP address. After applying the new IPv4 address, please re-login the router at the new router IP address.
Field
Default
Description
IPv4 address
192.168.30.1
The router's IP address
Choose from the below Class A~C private IP address ranges.
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.
Private IP address ranges
Class A: 10.0. 0.0 — 10.255. 255.255
Class B: 172.16. 0.0 — 172.31. 255.255
Class C: 192.168. 0.0 — 192.168. 255.255
Do not enter the IPv4 gateway unless the 4G router connects another master gateway in the local network.

DHCP Server

The DHCP server can automatically configure the TCP/IP settings of connected devices and lease out an IP address from the available IP pool.
On the LAN interface configuration page, scroll down and find the section of the DHCP server. Modify the DHCP server settings under the tab of General Setup.
Field
Default
Description
Start
100
The start of DHCP IP pool.
For example, if the router’s LAN IP is 192.168.30.1 and netmask is 255.255.255.0, a valid IP address should be in the range of [192.168.30.0…192.168.30.254]
* 192.168.30.255 is a special unavailable address.
Limit
150
Define the IP addresses the DHCP server can lease out.
Continuing from the above example: if the start address is 192.168.30.100 and the server can lease out 150, available addresses will be from 192.168.30.100 to 192.168.30.249.
Lease time
12 hours
The duration of an IP lease. Leased-out addresses will expire after the specified period, and 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 minimal amount of time that can be specified is 2min (2m).

Static IP

If the DHCP server was disabled, we could access the router with a static IP address. Below is an example of static IP address settings. Make sure the gateway IP address and subnet mask address match with the above router configurations.
Computer IP: 192.168.30.100 (Inside the default DHCP range of 100~249) Subnet Mask: 255.255.255.0 (also called 24 on Windows) Gateway (Router IP): 192.168.30.1

How to configure a static IP address?

On iPhone: Goes to "Settings > Wi-Fi > Advanced". On Android phone: Goes to "Settings > WLAN > Advanced". On Mac: Goes to "System Preferences > Network > Wi-Fi > Advanced > TCP/IP".
On Windows 10 Goes to "Start > Control Panel > Network & Internet > Change Adapter Settings. Change the "Local Area Connection > Properties (on the right click) > TCP/IPv4 > Properties > General". Enter the above static IP address, subnet mask, and gateway. Click "Ok" to exit settings.

2 WAN (eth0)

The WAN interface is bound to the physical eth0 port. To input the landline Internet signal to the 4G router, you can use a LAN cable to connect to the WAN port.
DHCP client protocol is assigned on the WAN interface. It can automatically obtain the IP address after connected to the LAN port on the internet router or landline modem.

3 Mobile (wwan0)

It's bound to the 4G LTE modem. Please refer to the above step 4.4.2 to configure the Mobile interface.

4 WWAN (Wi-Fi Client)

This is the virtual interface bound to the Wi-Fi relay connection. The WWAN interface will appear after successfully connected the 4G router to another Wi-Fi hotspot. Please refer to the above step 4.3.3 to set a Wi-Fi relay connection.
