4.5 LAN and WAN
The EZR34T-5G is a standalone router with LAN WAN interfaces and a DHCP server. After logging into the router, go to Network > Interfaces to view and manage the LAN and WAN interfaces.
Rx/Tx indicates the real-time data stream instead of the speed.
The color on the interface is not corresponding to its connection status.
Intranet LAN
LAN, or local area network, enables the 5G mobile internet to all the devices connected to the 5G CPE router. To edit the router IP address and DHCP server settings, go to Network > Interface, and click the Edit button on the first row of the LAN interface.
Router IP
When there is more than one router in the same network and working on the same IP range of 192.168.30.x, please change their router IP to a different one to avoid IP conflicts.
After clicking the Edit button on the LAN interface, go to the tab of General Setup.
Protocol: Always use the "Static address" protocol for the LAN interface.
IPv4 Address: It's the EZR34T router's IP address. Ensure it ably to the private IP formats when changing it.
IPv4 Netmask: It defines how "large" the LAN network is.
IPv4 Broadcast: The DHCP clients use the 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
Physical Ports
There are two physical RJ45 ports on the router. eth0.1 is bound to the LAN interface, and eth0.2 is bound to the WAN interface. Both eth0.1 and eth0.2 supports PoE power input.
The LAN interface should be bound to eth0.1 with no change when you use a PoE injector to output Ethernet signals. You can also bind eth0.2 to the LAN interface when you need two of the LAN ports.
Firewall Zone
Do not change the firewall settings unless you have configured the alternative firewall zone correctly.
DHCP Server
The DHCP server can automatically configure connected devices' TCP/IP settings 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.
Ignore Interface: Enable this checkbox will turn off the router's DHCP server. The connected devices will no longer be able to obtain local IP from the router and can not access the mobile internet.
Advanced Settings > Force: Enable this option when there is more than one DHCP server in the entire network.
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 a new DHCP lease must be requested. 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). Use Infinite to assign lease time forever. |
Static IP Address
If the DHCP server was disabled on the router, we could access the router with a static IP address. Below is an example of static IP address settings. Ensure the gateway IP address and subnet mask address match the 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.
WAN Network
WAN stands for Wide Area Network. The EZR34T router's WAN network consists of the physical WAN port, WiFi relay link, and mobile modem.
The physical WAN port is bound to RJ45 port eth0.2. When the PoE injector is linked to the WAN port, you can input a landline internet to the router.
The WAN interface (eth0.2) has enabled the DHCP client protocol, and it will automatically obtain the IP address and internet traffic from the source router.
