4.5 Local Networks

The local network settings on EZR34-012 router.

After logging in to the router admin panel, go to "Network > Interfaces" to view and manage the network interfaces. The local network is handled 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.

1 LAN (bar-lan)

The LAN interface controls the local intranet network. It is bound to the physical eth0.1 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.




IPv4 address

The router's IP address

Choose from the below Class A~C private IP address ranges.

IPv4 netmask

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

IPv4 broadcast


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 to 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.






The start of DHCP IP pool.

For example, if the router’s LAN IP is and 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 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: (Inside the default DHCP range of 100~249) Subnet Mask: (also called 24 on Windows) Gateway (Router IP):

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 (eth0.2)

The WAN interface is bound to the physical eth0.2 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 connecting 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 connecting the 4G router to another Wi-Fi hotspot. Please refer to the above step 4.3.3, to set up a Wi-Fi relay connection.
