4.2 Network Interfaces

The network interfaces on the EZR23 router.
After log in to the router, go to Network > Interfaces to view and manage the network interfaces.
The brief information of each interface is listed under the second column, including MAC address, Rx (Download), Tx (Upload), Uptime, and IP address.
Overview of EZR23 network interfaces
Do not Stop the LAN interface or Delete any of the interfaces. It will make the router mis-functioning.
  • The color on each interface is not corresponding to its connection status.
  • Rx/Tx indicates the realtime data stream instead of the speed of internet or intranet.

4.2.1 - Mobile_4 (wwan0)

This is a virtual interface that only appears when the Mobile (wwan0) interface is using QMI protocol and connected to mobile internet networks. You can find the IP address obtained by the mobile modem on the row of IPv4. The Uptime is the lasting connection period with the mobile network, which depends on the timeout period released from the mobile carrier.

4.2.2 - LAN (bar-lan)

This is the physical interface of the local intranet network. It is assigned to the physical RJ45 port eth1 by default, which also has the PoE power input. Refer to the below section to configure the local intranet networks.

4.2.3 - Mobile (wwan0)

This interface is bind to the physical mobile modem. On the row of SIM, you can find the current working SIM card. The QMI row indicates the mobile operator, mobile network, and signal strength (dBm). If it's showing UNKNOWN, there is no SIM card or SIM card installed incorrectly.
The 4G router automatically connects mobile network when started up, and you can manually Stop or Connect the 4G modem by clicking the related buttons. After successfully connected to the 4G network, Rx/Tx shows the realtime data stream and shows the IPv4 IP address obtained from the mobile carrier. The IP address shows on the Mobile_4 interface while using the default QMI protocol.

4.2.4 - WAN (eth0)

The WAN port is bind to the eth0 RJ45 port by default. To input the WAN Internet signal from the PoE port into the EZR23 router, you can bind eth1 to the WAN port on the WAN > physical settings.
DHCP client protocol is enabled on the WAN interface, and it can automatically obtain the IP address after connected to the LAN port on the internet router or landline modem.

4.2.5 - WWAN (Wi-Fi Client)

This is the virtual interface for the Wi-Fi relay connection. The WWAN interface will appear after successfully connected the EZR23 router to another Wi-Fi master hotspot.
